## Abstract

A film-attached solid electrolyte membrane includes: a film having a surface that has a contact angle with respect to acetonitrile in a range from 35 to 75 degrees and a contact angle with respect to chloroform in a range from 15 to 40 degrees; and a solid electrolyte membrane in contact with the surface of the film. A manufacturing method of a film-attached solid electrolyte membrane includes: coating a solid-electrolyte-membrane-forming composition on a surface of a film that has a contact angle with respect to acetonitrile in a range from 35 to 75 degrees and a contact angle with respect to chloroform in a range from 15 to 40 degrees; and curing the coated solid-electrolyte-membrane-forming composition to form a solid electrolyte membrane.

## Claims
