NOVELTY - Electrically conductive adhesive composition, comprises: electrically conductive particles containing a metal of which melting point is less than or equal to 220 degrees C; a thermosetting resin; and a thermal cationic polymerization initiator.    USE - The electrically conductive adhesive composition is useful: for electrically connecting an electrode of a solar battery cell and a wiring member; a connection structure; for producing a solar battery module (all claimed); in heterojunction solar batteries; in crystalline silicon solar batteries; and in the back-surface electrode type (back contact type) solar battery cells.    ADVANTAGE - The electrically conductive adhesive composition provides good electric properties, good connection strength in a connection under the conditions of low-temperature and short-time, and good connection reliability in a high-temperature and high-humidity test.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a connection structure (30) comprising a solar battery cell, and a wiring member electrically connected with an electrode of the solar battery cell via the electrically conductive adhesive composition or its cured product;    (2) producing a solar battery module comprising arranging an electrode of a solar battery cell (20) and a wiring member (4) so as to face each other via the electrically conductive adhesive composition, laminating encapsulants (2) on a light receiving surface side of the solar battery cell and on a back surface side opposite to the light receiving surface, laminating a glass member (1) on the encapsulant at the light receiving surface side of the solar battery cell, laminating a protective film on the encapsulant at the back surface side of the solar battery cell, and heating the laminate having the glass member and the protective film to electrically connect the electrode of the solar battery cell and the wiring member and also to encapsulate the solar battery cell; and    (3) a solar battery module comprising a solar battery cell, a wiring member electrically connected to an electrode of the solar battery cell via the electrically conductive adhesive composition or its cured product, encapsulants laminated each on a light receiving surface side of the solar battery cell and a back surface side opposite to the light receiving surface, a glass member laminated on the encapsulant at the light receiving surface side of the solar battery cell, and a protective film laminated on the encapsulant at the back surface side of the solar battery cell.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of producing the solar battery module.
