An accumulator having an oil return pipe is provided to easily recollect oil by installing the oil return pipe on the bottom surface of the accumulator and to easily install a suction pipe and an exhaust pipe by modifying the upper structure of the accumulator. An accumulator comprises a main body(100) separating gas-phase and liquid-phase coolant discharged from an evaporator of an air conditioner; a suction pipe(200) inserted at one side of the main body and elongated into the main body to inflow mixed gas-phase and liquid-phase coolant into the main body; an exhaust pipe(300) inserted from the lower surface of the main body to be elongated into the main body to a predetermined length so as to discharge gas-phase coolant separated at the inner side of the main body to a compressor of the air conditioner; and an oil return pipe(400) connected with the lower surface of the main body at one side to suck oil gathered on the lower surface of the main body and connected with one side of the outer peripheral surface of the exhaust pipe at the other side to discharge oil sucked from the lower surface of the main body together with the gas-phase coolant.
