An intercooler has a case through which supercharging air passes, and a heat exchanger 4 mounted inside the case which allows heat exchange between the supercharging air and a cooling fluid. A frame body 15 is provided at the circumferential edges of air passage portions of the heat exchanger 4 on a supercharging air intake side and a supercharging air outlet side to reduce the gap between the heat exchanger and the inner wall of the case. The heat exchanger 4 has a pair of tanks 43 and 44 , tubes communicating between the tanks, and a plurality of fins 46 set along the tubes, and assumes a structure that allows the supercharging air to pass through the heat exchanger a plurality of times by sequentially passing through blocks formed by dividing a heat exchanging unit 4 A into a plurality of blocks with partitioning plates 15 d. |
