Document Type and Number:
Japanese Patent JP6730016
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a constitution in which an electrochemical element incorporated in a plate member such as a card has a sufficient strength when a bending deformation is caused in the plate member.SOLUTION: A laminate-type battery (3) is disposed in a flexible card (1). The laminate-type battery (3) includes: an electrode body including a positive electrode and a negative electrode; a sheet-like laminate film outer packaging body having an outer peripheral side that is welded while the laminate film outer packaging body covers the electrode body; and a positive electrode connection terminal (41) and a negative electrode connection terminal (42), each having one end side connected to the electrode body and the other end side extending from the laminate film outer packaging body to the outside. At least one of the positive electrode connection terminal (41) and the negative electrode connection terminal (42) has a bent portion (41c) formed by being bent in a thickness direction.SELECTED DRAWING: Figure 1
