A lead member for use in a nonaqueous electrolytic electricity storage device which can prevent intrusion of moisture while exhibiting good bendability. A method for producing such a lead member and a nonaqueous electrolytic electricity storage device are also provided. Lead members (21a, 21b) for use in a nonaqueous electrolytic electricity storage device where an electrode body consisting of a positive electrode (11a) and a negative electrode (11b) and a nonaqueous electrolyte medium (13) are contained in an enclosure bag (6) made of a multilayer film (10) including a metal foil layer (8) comprise lead conductors (22a, 22b) connected with the electrode body, and insulators (23a, 23b) bonded to the lead conductors (22a, 22b) and then bonded to the inner surface of the enclosure bag (6). The insulators (23a, 23b) are formed by joining single layer resin films (crosslinked film (25)) of 20-40 µm thick together while sandwiching the lead conductors (22a, 22b) and their entirety is crosslinked. |
