The utility model discloses a film capacitor, including capacitor element who has the zinc layer and the lead group of drawing forth capacitor element's electrode, wherein, at least one lead wire spouts the zinc welding with the zinc layer in the lead group. Because capacitor element's zinc layer all is pure zinc with the material of spraying point usefulness, it is more firm with the combinationdegree of tin that the combination degree of zinc and zinc compares zinc. The pure zinc welding lead of spraying, lead wire are just inlayed in the environment the inside of pure zinc, combine together with capacitor element, reach extraction electrode's purpose, and capacitor element can not harmd to this kind of mode to the die pull of capacitor element with the lead wire has been improved. 本实用新型公开了种薄膜电容器，包括具有锌层的电容器元件和引出电容器元件的电极的引线组，其中，所述引线组中至少个引线与锌层喷锌焊接。由于电容器元件的锌层与喷涂点用的材质都是纯锌，锌与锌的结合度比锌与锡的结合度更牢固。喷涂纯锌焊接引线，引线就镶嵌在纯锌的环境里面，与电容器元件结合到起，达到引出电极的目的，这种方式不会损伤电容器元件，并且提高了电容器元件与引线的拉拔力。
