A scroll compressor comprising: a casing to which a refrigerant suction pipe and a refrigerant discharge pipe are connected; a compression part disposed in an inner space of the casing, and configured to compress refrigerant in a compression chamber between a non-orbiting scroll and an orbiting scroll by receiving rotational force of a motor part through a rotating shaft; and a high and low pressure separation plate disposed at one side of the compression part in an axial direction, dividing the inner space of the casing into a low-pressure part connected to the refrigerant suction pipe and a high-pressure part connected to the refrigerant discharge pipe, and having a through hole formed through a central portion thereof to guide refrigerant discharged from the compression part toward the high-pressure part, wherein the high-pressure part is provided with a discharge guide (1121, 115e) to guide the refrigerant discharged from the compression part to the refrigerant discharge pipe, the high and low pressure separation plate includes an inclined surface portion extending from a central portion to a rim thereof to be downwardly inclined, and a first protrusion protruding from the inclined surface portion and extending in a radial direction, wherein the discharge guide (1121, 115e) extends by a preset height toward the high and low pressure separation plate from at least an inner surface of the casing in the high-pressure part, one side surface of the high and low pressure separation plate facing the high-pressure part, wherein the discharge guide extends to surround at least partially the through hole, and a portion of the discharge guide is open radially toward the refrigerant discharge pipe, and characterized in that a first central angle (α1) of the discharge guide, which is formed by connecting the axial center of the rotating shaft to both ends of the discharge guide, is greater than a second central angle (α2) of the first protrusion, which is formed by connecting the axial center of the rotating shaft to both ends of the first protrusion. a casing to which a refrigerant suction pipe and a refrigerant discharge pipe are connected; a compression part disposed in an inner space of the casing, and configured to compress refrigerant in a compression chamber between a non-orbiting scroll and an orbiting scroll by receiving rotational force of a motor part through a rotating shaft; and a high and low pressure separation plate disposed at one side of the compression part in an axial direction, dividing the inner space of the casing into a low-pressure part connected to the refrigerant suction pipe and a high-pressure part connected to the refrigerant discharge pipe, and having a through hole formed through a central portion thereof to guide refrigerant discharged from the compression part toward the high-pressure part, wherein the high-pressure part is provided with a discharge guide (1121, 115e) to guide the refrigerant discharged from the compression part to the refrigerant discharge pipe, the high and low pressure separation plate includes an inclined surface portion extending from a central portion to a rim thereof to be downwardly inclined, and a first protrusion protruding from the inclined surface portion and extending in a radial direction, wherein the discharge guide (1121, 115e) extends by a preset height toward the high and low pressure separation plate from at least an inner surface of the casing in the high-pressure part, one side surface of the high and low pressure separation plate facing the high-pressure part, wherein the discharge guide extends to surround at least partially the through hole, and a portion of the discharge guide is open radially toward the refrigerant discharge pipe, and characterized in that a first central angle (α1) of the discharge guide, which is formed by connecting the axial center of the rotating shaft to both ends of the discharge guide, is greater than a second central angle (α2) of the first protrusion, which is formed by connecting the axial center of the rotating shaft to both ends of the first protrusion.
