To provide a polymer solid electrolyte having a high ion conductivity at a practical application level, and to provide a polymer solid electrolyte battery equipped with this polymer solid electrolyte.
The polymer solid electrolyte contains: a multibranched polymer including a core part having three or more of branchded chains and an arm moiety having a repeating unit (a) represented by formula (a1); and an electrolyte salt. In the above formula, R100, R200 and R300 are each independently a hydrogen atom or a hydrocarbon group of C1-C10, R100 and R300 may bond to form a ring, R4a, R4b are each independently a hydrogen atom or a methyl group, R500 is a hydrogen atom, a hydrocarbon group, an acyl group or a silyl group, s is an integer of 2-100, and each of groups represented by formula: -CH(R4b) -CH(R4a) -O- may be same or different.
