The utility model provides a battery monomer, a battery and a power utilization device, and belongs to the technical field of batteries. The battery monomer comprises a shell, a pressure relief mechanism and a protection piece, the shell is provided with a stepped hole communicated with the interior of the shell, the stepped hole comprises a first hole section and a second hole section which are arranged in the first direction, and the first hole section is located on the side, away from the interior of the shell, of the second hole section. The pressure relief mechanism and the protection piece are arranged in the second hole section and the first hole section respectively, and the protection piece covers at least part of the pressure relief mechanism. According to the single battery with the structure, the phenomenon that the protection piece protrudes out of the outer surface of the shell can be reduced, on one hand, the protection piece can be well protected, so that the risk of abrasion or damage of the
