ABSTRACT:
First and second communicating holes are formed in a first formed plate 11, and first and second communicating holes are also formed in a second formed plate 12. The first and second formed plates 11 and 12 are joined to each other to form a joined body 8. When a plurality of joined bodies 8 are stacked, a heat exchanging section 7 is formed that is provided with a plurality of flow pipes 34 in which the first communicating holes are connected with each other in the stacking direction and the second communicating holes are also connected with each other. In the plurality of flow pipes 34 of the heat exchanging section 7, oil passage 35 in which engine oil flows in the stacking direction is formed, and further around the plurality of flow pipes 34, a plurality of cooling water passages 36 in which engine cooling water flows are formed.
