Abstract
Abstract A primary invention is a solid polymer electrolyte including an ionic salt and a compound able to dissolve the ionic salt and having a crosslink network structure. A crosslink network structure is formed by polymerizing a two-functional acryloyl compound having two acryloyl groups with a one-functional acryloyl compound having one acryloyl group. In this solid polymer electrolyte, the crosslink network structure has a skeleton in which the one-functional acryloyl compound spreads into branches. Since molecular movement of this branched skeleton is active, its flexibility is improved.
