PROBLEM TO BE SOLVED: To provide a diphenylsulfone compound for a polymer electrolyte, in which swelling can be suppressed, a polymer electrolyte, a membrane electrode joined body, a solid polymeric fuel cell, and a production method of a polymer electrolyte.SOLUTION: A diphenylsulfone compound for a polymer electrolyte is expressed by general formula (1). In the formula, Rand Reach independently represent a linking group selected from the group consisting of -(CH)-, -O-(CH)-, -S-(CH)-, -NH-(CH)-, -(CF)-, -O-(CF)-, -S-(CF)- and -NH-(CF)-, where a represents an integer of 2 or more; Xand Xeach independently represent a halogen atom; and Yand Yeach independently represent an atom selected from a group consisting of group 1 elements and group 2 elements. |
