A heat exchanging apparatus has a flow path with air tightness formed by joining a second sheet to a first sheet formed by bending the first sheet by stamping and fluid introduced into the flow path impinges on a wall of the flow path to perform heat exchange. A material constituting the flow path may be a metal sheet or an electrically-conductive plastic, and a small-sized and light-weight heat exchanging apparatus can be manufactured at a low cost. |
