The invention discloses a thin film capacitor which comprises a capacitor element with a zinc layer and a lead group for leading out an electrode of the capacitor element; in the lead group, at least one lead is welded with the zinc layer in a zinc spraying manner. As the zinc layer of the capacitor element and a spraying point are made of pure zinc, the binding degree between zinc and zinc is firmer than that between zinc and tin. When being welded in a pure zinc spraying manner, the lead is embedded in a pure zinc environment and is combined with the capacitor element together to realize the purpose of leading out the electrode. In such a manner, the capacitor element cannot be damaged, and the pulling forces of the capacitor element and the lead are improved. 本发明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。
