(57) A heat exchanger (2) includes a first member (4) and a second member (5). The first member (4) is provided with a main body (4a) and a heat transfer accelerating portion (3) formed on the main body (4a) as one unit. The second member (5) is formed with a recess (5a) dented from a reference surface (51) and functioning as a flow channel (21). The first member (4) and the second member (5) are joined with each other at the reference surface (51) in a state where a part, which deviates from the recess (5a) when the first and second members (4, 5) are joined, of the heat transfer accelerating portion (3) of the first member (4) is cut off and the rest of the heat transfer accelerating portion (3) is inserted into the recess of the second member (5).
