摘要

A check valve (100) that opens and closes by causing a valve element (112) to come into contact with and separate from a valve seat (104) and thereby controls a flow of fluid that flows in through an inlet (101) and flows out through an outlet (102). The check valve (100) has: the inlet (101) provided at a downside thereof; the outlet (102) provided at an upside thereof; the valve seat (104) formed to surround the inlet (101); the valve element (112) configured to be able to come into contact with and separate from the valve seat (104) vertically; and a guide portion (105) that has a fluid guide surface (118) horizontally guiding a fluid flowing in through the inlet (101), and a valve element guide surface (111) provided on a side surface thereof, the valve element guide surface (111) vertically guiding the valve element.
