A polyparaphenylene hydrocarbon electrolyte having a structure represented by a formula (1), a manufacture method therefore, and a polyparaphenylene usable as a raw material for manufacturing the polyparaphenylene hydrocarbon electrolyte, as well as a electrolyte membrane, a catalyst layer and a solid polymer fuel cell that employ the polyparaphenylene hydrocarbon-based electrolyte. In the formula, A is an integer of (1) or greater; B is an integer of 0 or greater; and C is an integer of 1 to 10. X represents a direct bond or an oxygen atom, which is arbitrarily assignable in repetitions. At least one of Y1s represents a proton-conducting site, and the rest of Y1s each represent a hydrogen atom or a proton-conducting site, which is arbitrarily assignable in repetitions. The proton-conducting site is made up of -SO3H, -COOH, -PO3H2 or -SO2NHSO2R (R is an alkyl chain or a perfluoroalkyl chain). |
