To produce a solid polymer electrode capable of improving lowness of an ionic conductivity and inferiority of low temperature characteristics and useful for an electric cell, etc., by using a bifunctional monomer having dibenzocrown ether skeleton as a side chain.
This solid polymer electrode comprises a complex containing an alkali metal in an organic polymer obtained by cross linking a monomer having a skeleton forming a dibenzocrown ether structure as a side chain. Further, the polymer is obtained by polymerizing and crosslinking the monomer having the skeleton forming the dibenzocrown ether structure of the formula [R is a divalent organic group; X is a monovalent organic group polymerizable by irradiation of energy rays; (l) and (m) are each 1-5] as a side chain, especially the monomer is preferably polymerized and crosslinked after the monomer is formed into a membrane shape in the presence of an alkali metal salt.
