Patent abstract
To provide a check valve which can be used even under a high temperature condition by overcoming a drawback “valve element sticking to sealing member” associated with high temperature use while enhancing heat resistance. An opening of a fluid path formed in a first body is brought into a closed state by bringing a valve element biased by a biasing member into contact with a sealing member. The sealing member is formed of a post-cured perfluoro elastomer packing. An annular sealing portion which is brought into line contact with the sealing member is formed on the valve element.
