Zusammenfassung:	To provide a working fluid for heat cycle which has a small temperature glide, a sufficiently low discharge temperature, high durability and less influence over global warming, and with which a heat cycle system excellent in the system maintenance properties and the cycle performance (capacity) is achieved, a composition for a heat cycle system, and a heat cycle system. A working fluid for heat cycle, which contains trifluoroethylene and difluoromethane, wherein the proportion of the total amount of trifluoroethylene and difluoromethane based on the entire amount of the working fluid for heat cycle is higher than 90 mass % and at most 100 mass %, and the mass ratio represented by trifluoroethylene/difluoromethane in the working fluid for heat cycle is from 41/59 to 59/41, a composition for a heat cycle system, and a heat cycle system employing the composition.
