Beschreibung
Zusammenfassung:	A positive electrode lead of the present invention comprises: a strip-shaped first lead half body electrically connected to a sealing body of a nickel-hydrogen secondary battery; a strip-shaped second lead half body electrically connected to a positive electrode of an electrode group of the nickel-hydrogen secondary battery; a PTC thermistor joined between the first lead half body and the second lead half body; and a protective member covering a portion of the positive electrode lead where the PTC thermistor is joined. The second lead half body includes a portion to be bent on the outer side of the portion covered with the protective member. A recessed groove is formed in the portion covered with the protective member and has a shape elongated in a direction intersecting with a bend line of the portion to be bent.
