A check valve is configured in such a manner that a valve body (112) comes into contact with and moves away from a valve seat (104) to thereby close and open the valve, controlling the flow of fluid flowing in from a flow inlet (101) and flowing out from a flow outlet (102). The check valve (100) is provided with: the flow inlet (101) provided in the lower part of the check valve; the flow outlet (102) provided in the upper part of the check valve; the valve seat (104) formed so as to surround the flow inlet (101); the valve body (112) configured so that the valve body (112) is capable of moving vertically, coming into contact with and moving away from the valve seat (104); and a guide section (105) having at the lower part thereof a fluid guide surface (118) for horizontally guiding fluid having flowed in from the flow inlet (101), the guide section also having at a side surface thereof a valve body guide surface (111) for vertically guiding the valve body. |
