<P>PROBLEM TO BE SOLVED: To provide an electrode for a secondary battery which can eliminate a possibility of a short circuit caused by the dislocation of an active substance while maintaining battery characteristics. <P>SOLUTION: The electrode of the secondary battery is composed of a three dimensional metal porous body and a mixture containing an active substance and a binding agent, and the mixture is filled in the three dimensional porous body. The electrode is composed of a first filled-in portion and a second filled-in portion which has a larger content of the binding agent than the first filled-in portion and has an approximately uniform distribution of the binding agent in a thickness direction, and a non-filled-in portion having no filled-in mixture agent, and at least one end of the second filled-in portion is made to contact closely with the non-filled-in portion, and the non-filled-in portion constitutes at least one of end sides. <P>COPYRIGHT: (C)2009,JPO&INPIT |
