There is provided a battery and a negative electrode for the battery, which are capable of being simply produced by a smaller number of steps. The battery includes: a battery can ( 7 ); a negative electrode plate for battery ( 21 ), the negative electrode plate having a paste-like material which contains an active material and which is provided on the entire surface of a rectangular conductive porous substrate including edge portions ( 22 a) extending along long sides of the substrate, the negative electrode plate being wound in a cylindrical shape to be inserted into the battery can; and a plate-shaped collector ( 28 ) having ribs ( 31 ) formed by raising part thereof, the ribs being resistance-welded to one of the edge portions of the conductive porous substrate while the paste-like material provided on the edge portions.
