A scroll compressor comprising: a compression mechanism including a fixed scroll in which a fixed end plate and a spiral fixed lap are integrated, the fixed end plate having a fixed slideable contact surface, a radially orbiting scroll in which a movable end plate and a spiral movable lap are integrated, the movable end plate having a moveable slideable contact surface, wherein the fixed lap and the movable lap are engaged with each other and form a compression chamber, a suction space being formed as an outer peripheral portion of the compression chamber communicating with a suction port, the fixed slideable contact surface and the movable slideable contact surface are in pressure contact with each other around the compression chamber, an oil groove to which high-pressure refrigerating machine oil is supplied is located in the fixed slideable contact surface and extends around part of the compression chamber, during orbiting of the orbiting scroll, at least in the suction space (50 L), a radially outer seal length from a radially outer peripheral edge of the oil groove in the fixed slideable contact surface to a radially outer edge of the movable end plate is smaller than a radially inner seal length from a radially inner peripheral edge of the oil groove to a peripheral edge of the compression chamber, characterized in that a portion of the oil groove corresponding to an inflow end of high-pressure oil is a proximal portion, a portion of the oil groove formed around the suction space (50 L) is a distal portion having a distal end, and at least one of a radial width or a depth of the distal portion is larger than that of the proximal portion. a compression mechanism including a fixed scroll in which a fixed end plate and a spiral fixed lap are integrated, the fixed end plate having a fixed slideable contact surface, a radially orbiting scroll in which a movable end plate and a spiral movable lap are integrated, the movable end plate having a moveable slideable contact surface, wherein a fixed scroll in which a fixed end plate and a spiral fixed lap are integrated, the fixed end plate having a fixed slideable contact surface, a radially orbiting scroll in which a movable end plate and a spiral movable lap are integrated, the movable end plate having a moveable slideable contact surface, wherein the fixed lap and the movable lap are engaged with each other and form a compression chamber, a suction space being formed as an outer peripheral portion of the compression chamber communicating with a suction port, the fixed slideable contact surface and the movable slideable contact surface are in pressure contact with each other around the compression chamber, an oil groove to which high-pressure refrigerating machine oil is supplied is located in the fixed slideable contact surface and extends around part of the compression chamber, during orbiting of the orbiting scroll, at least in the suction space (50 L), a radially outer seal length from a radially outer peripheral edge of the oil groove in the fixed slideable contact surface to a radially outer edge of the movable end plate is smaller than a radially inner seal length from a radially inner peripheral edge of the oil groove to a peripheral edge of the compression chamber, characterized in that a portion of the oil groove corresponding to an inflow end of high-pressure oil is a proximal portion, a portion of the oil groove formed around the suction space (50 L) is a distal portion having a distal end, and at least one of a radial width or a depth of the distal portion is larger than that of the proximal portion.
