Abstract
Provided are a three-way valve for flow rate control and a temperature control device, which have improved sealing performance against a fluid having a low temperature of about −85° C. as compared to a case in which a pressure applying portion does not include a communication member having a cylindrical shape with both end portions in a longitudinal direction sealed by sealing means including a coating member, which has a substantially U-shaped cross section and is made of a synthetic resin, and is urged in an opening direction by a spring member made of a metal. The pressure applying portion includes the communication member having a cylindrical shape, which allows inner surfaces of first and second valve port forming members and first and second outflow ports to communicate with each other, and in which both end portions in the longitudinal direction are each sealed by the sealing means including the coating member, which has a substantially U-shaped cross section and is made of a synthetic resin, and is urged in the opening direction by the spring member made of a metal.
