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 (L1) 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 (L2) 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 (L1) 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 (L2) 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 . <EOS>
