In order to prevent deformation of a side member due to thermal stress in a heat exchanger in which a high-temperature body to be cooled circulates, a side member (5) is formed in the shape of a groove, the cross section of which has side wall parts (5d) and a base part (5c) along the entire length in the lengthwise direction of a main body part (5a), and both ends of the side member in the lengthwise direction are provided with a stepped part (5b), which is formed as a step toward the outside of a core (3), and one or more brace-like ribs (9), which integrally connect the tip end and the base part of the stepped part (5b) in a slanting manner. |
