NOVELTY - The test jig has a jig main body (100) and an insertion section at the end portion of jig main body and into which an electrode lead (1) is inserted. A fixing member (200) is detachably coupled to insertion section to fix the electrode lead inserted to insertion section. The insertion section has insertion faces outwardly extending in inclined state from both end portions of jig main body, and coupling faces extending from insertion faces toward insides of jig main body and brought into contact with the fixing member.    USE - Test jig for implementing tensile test for ultrasonic-welded portion of electrode lead of cell in secondary battery for equipment. Uses include but are not limited to mobile phone, computer, portable DVD, small personal computer (PC), electric vehicle, and hybrid vehicle.    ADVANTAGE - Reduces cost and enhances work efficiency since electrode leads are fixedly inserted into both ends of the test jig to perform tensile test on ultrasonic-welded portion of the electrode lead without using additional cell. The insertion face is inclined outwardly, and electrode lead is slantly placed to increase work efficiency for the tensile test. Eliminates need to use the additional cell by virtue of the jig main body manufactured in the shape of the cell. Increases fixing force and prevents electrode lead from being damaged and from having tensile force due to the pressing force since buffer portion is supported by the surface of electrode lead to provide pressing force more uniformly over the entire surface of electrode lead when coupling the fixing member to the jig main body. The test jig efficiently adjusts bolt coupling holes to enhance work efficiency and reduce the mobility of fixing member to increase fixing force when jig main body and fixing member are coupled. The latch portion uniformly adjusts the heights of electrode leads by allowing end portions of electrode leads inserted to the insertion faces to be latched and thus equally adjust withdrawal lengths of the electrode leads inserted to the test jigs. Minimizes waste of unnecessary costs and enhances work efficiency since tensile test is performed on ultrasonic-welded portion of electrode lead without use of additional cell.
