A scroll compressor, comprising: a fixed scroll and an orbiting scroll, each having an end plate (31, 41), and a spiral lap (32, 42) protruding from a front surface of the end plate (31, 41), wherein the fixed scroll and the orbiting scroll mesh with each other in such a manner that an end face (42a, 32a) of the lap (42, 32) of one of the fixed scroll or the orbiting scroll faces the front surface of the end plate (31, 41) of the other of the fixed scroll and the orbiting scroll to form a compression chamber, the scroll compressor is connected to a refrigerant circuit for performing a refrigeration cycle to compress a refrigerant sucked into the compression chamber, the scroll compressor includes an injection passage through which an intermediate pressure refrigerant is supplied to the compression chamber in the course of compression, refrigeration oil separated from a refrigerant discharged from the scroll compressor is supplied to the injection passage together with the intermediate pressure refrigerant, a bottom land (31a, 41a) which is part of the front surface of the end plate (31, 41) facing the lap (42, 32) has an intermediate bottom region (36, 46) facing the compression chamber communicating with the injection passage, and a suction side bottom region (35, 45) which is closer to an outer end of the lap (42, 32) than the intermediate bottom region (36,46) is, characterised in that a clearance between the suction side bottom region (35, 45) and the end face (42a, 32a) of the lap (42, 32) facing the suction side bottom region (35, 45) is larger than a clearance between the intermediate bottom region (36, 46) and the end face (42a, 32a) of the lap (42, 32) facing the intermediate bottom region (36, 46). a fixed scroll and an orbiting scroll, each having an end plate (31, 41), and a spiral lap (32, 42) protruding from a front surface of the end plate (31, 41), wherein the fixed scroll and the orbiting scroll mesh with each other in such a manner that an end face (42a, 32a) of the lap (42, 32) of one of the fixed scroll or the orbiting scroll faces the front surface of the end plate (31, 41) of the other of the fixed scroll and the orbiting scroll to form a compression chamber, the scroll compressor is connected to a refrigerant circuit for performing a refrigeration cycle to compress a refrigerant sucked into the compression chamber, the scroll compressor includes an injection passage through which an intermediate pressure refrigerant is supplied to the compression chamber in the course of compression, refrigeration oil separated from a refrigerant discharged from the scroll compressor is supplied to the injection passage together with the intermediate pressure refrigerant, a bottom land (31a, 41a) which is part of the front surface of the end plate (31, 41) facing the lap (42, 32) has an intermediate bottom region (36, 46) facing the compression chamber communicating with the injection passage, and a suction side bottom region (35, 45) which is closer to an outer end of the lap (42, 32) than the intermediate bottom region (36,46) is, characterised in that a clearance between the suction side bottom region (35, 45) and the end face (42a, 32a) of the lap (42, 32) facing the suction side bottom region (35, 45) is larger than a clearance between the intermediate bottom region (36, 46) and the end face (42a, 32a) of the lap (42, 32) facing the intermediate bottom region (36, 46).
