Zusammenfassung:	A positive electrode lead 50 of the present invention comprises: a strip-shaped first lead half body 51 electrically connected to a sealing body 30 of a nickel-hydrogen secondary battery 1; a strip-shaped second lead half body 52 electrically connected to a positive electrode 21 of an electrode group 20 of the nickel-hydrogen secondary battery 1; a PTC thermistor 53 joined between the first lead half body 51 and the second lead half body 52; and a protective member 54 covering a portion of the positive electrode lead 50 where the PTC thermistor 53 is joined. The second lead half body 52 includes a portion to be bent on the outer side of the portion covered with the protective member 54. A recessed groove 524 is formed in the portion covered with the protective member 54 and has a shape elongated in a direction intersecting with a bend line B of the portion to be bent.
