The capacity of this secondary cell is hardly decreased when charging and discharging are repeated. The material of the cathode and/or anode of the cell is either bonded to the surface of the collector by a binder containing a bridged polymer or formed by coating on the collector a compound containing an active material and a polymer compound binder which contains a fluoric polymer compound which can be cured by radiation application. After the coating, radiation is applied to the material to cure the fluoric polymer compound. <IMAGE>
