PROBLEM TO BE SOLVED: To provide superior durability and charge transport performance by including a cross-linked polymer obtained by reacting a nitrogen-containing polymer compound with a compound having a specified structure. SOLUTION: This electrolyte composition comprises a cross-linked polymer obtained by the reaction of an electrophilic agent represented by formula I (X represents a desorption group, Q represents an allylene group or the like, Y represents an s-valent connecting group, and (s) represents an integer of 2 to 4) with a nitrogen-containing polymer compound. In the electrophilic agent, Y is preferably a phenylene group, when X is a halogen atom or the like, and Q is an arylene group, preferably, in the electrophilic agent, and an alkylene group when (s) is 2. The nitrogen-containing polymer compound preferably has a repeat unit represented by formula II. In the formula, R1 represents H or the like, L represents a 2-valent connecting group, Z represents a nitrogenous heterocyclic group, E represents a repeat unit derived from a compound having an ethylenic unsaturated group, (t) represents 0-1, (x) represents 5-100 wt.%, and (y) represents 0-95 wt.%. The electrophilic agent is desirably set to 5-200 mol% with respect to the reactive nitrogen atom of the nitrogen-containing polymer compound. |
