NOVELTY - The apparatus (1) has a press unit (4) that presses the workpiece (W) against support stand (2) from an upper side, so that the workpiece is pinched between support stand and press unit at the time of the heating of the interconnector by main heating unit (3). The support stand is connected between interconnector (I) and main heating unit, so that non-magnetically permeable material is not provided to the region (2a) whose width is equal to/or higher than the width of moving track of main heating unit which heats the interconnector centering on specific position.    USE - Apparatus for joining interconnector and solar cell element.    ADVANTAGE - The interconnector arranged at upper side/under solar cell element can be effectively heated from support stand, so that the main heating unit is arranged below the solar cell element. The press with a heating, interconnector, and solar cell element of an interconnector can be performed simultaneously, by installing the press unit above the solar cell element. Thus the bonding agent of the interconnector is hardened and can be pressed easily. The efficiency of the connection, uniform and effective soldering covering the interconnector full length can be increased and the cost reduction can be achieved. The collision and interference of the joining apparatus can be avoided, and the working speed can be enlarged. Thus the working efficiency of the joining apparatus can be improved. The framework for the heat history which is not added to the solar cell element can be positioned, so that the bending of the support stand and/or a solar cell element in positions other than the region can be effectively prevented. Thus the heating plate for keeping the temperature of the solar cell element constant can be provided.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for joining interconnector and solar cell element.
