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