1. A separator-integrated gasket for a fuel battery, comprising:
a lip-shaped gasket;
a first separator component made of a press-workable metal plate and including a first three-dimensional shape portion, the first separator component including a surface that is on a side opposite to a protruding direction of the first three-dimensional shape portion and on which a gasket attachment groove is formed, the gasket attachment groove holding the lip-shaped gasket;
a second separator component made of a press-workable metal plate and including a second three-dimensional shape portion, the second separator component including a surface that is on a side opposite to a protruding direction of the second three-dimensional shape portion and on which a three-dimensional shape fitting groove is formed, the three-dimensional shape fitting groove accommodating the first three-dimensional shape portion; and
a flat-shaped gasket held on an outer surface side at the second three-dimensional shape portion,
wherein the first three-dimensional shape portion and the second three-dimensional shape portion protrude in a same direction while mutually adjusted in positions on a flat surface, and
the first separator component and the second separator component are joined to each other while superposed over each other in a thickness direction.
