To provide a compressor capable of suppressing performance reduction by suppressing overheat of a low-pressure coolant flowing inside a suction pipe.

A compressor includes: a compression mechanism 15 including a fixed scroll 24 and a movable scroll 26; a suction pipe 18 which is connected to the fixed scroll 24 and sucks a coolant into a compression chamber 40; and a casing 10 in which a low-pressure space S2 is formed around the fixed scroll. In the low-pressure space S2, a part of the suction pipe 18 is disposed and the low-pressure coolant is present. In the suction pipe 18, a throttle portion and a suction portion are formed. In the throttle portion, a flow velocity of the coolant flowing inside the suction pipe 18 is increased. The suction portion makes the low-pressure space S2 communicate with the inside of the suction pipe 18 and sucks the coolant in the low-pressure space S2 into the suction pipe 18 by increasing the flow velocity of the coolant flowing inside the suction pipe 18.
