Abstract

PURPOSE:To increase mechanical strength by forming a full interpenetrating network structure where a first crosslinked network is entwined with a second crosslinked network. CONSTITUTION:More than 2 crosslinked-network-forming compounds selected from a group made up of acrylate, methacrylate, styrene and acryl compounds are different in reactivity, a faster reactive one of which compounds faster is reacted to form a first crosslinked network. Then, a structural body which has formed such a second crosslinked network that the first crosslinked network is entwined with a slow reactive compound, is made to contain ionic salt. It is thereby possible to get high polymer solid electrolyte having good mechanical strength.
