PROBLEM TO BE SOLVED: To provide a heat exchanger having further improved heat exchanging efficiency without depending only on the heat conductivity of the heat exchanger. SOLUTION: A jacket part 2 is mounted on the outer periphery of a reaction vessel 1. In the jacket part 2 on almost all outer peripheral face of the reaction vessel 1, a ceramic 4 is mounted which serves as a membrane heat emitting member for converting heat into a far infrared ray. The heat of a heat exchanged object in the reaction vessel 1 is conducted to cooled fluid in the jacket part 2 and emitted as the far infrared ray into the cooled fluid by the ceramic 4, thus improving the heat exchanging efficiency.
