A scroll compressor includes a casing, a scroll compression mechanism, a motor, a crankshaft, a bearing, a frame fixed to the casing; and an oil separation member fixed to the frame. The motor includes a stator and a rotor rotatable in a rotational direction. The bearing rotatably supports the crankshaft. The oil separation member suppresses mixing of a refrigerant and a lubricating oil. The frame supports the bearing and has first and second fixed legs fixed to the casing. The oil separation member has a first horizontal and inclined surfaces. The first inclined surface has a first inclined surface upstream portion and a first inclined surface downstream portion. The first inclined surface downstream portion is disposed higher than the first inclined surface upstream portion. The first horizontal surface, the first inclined surface, and the first fixed leg are disposed in order from upstream to downstream in the rotational direction.
