PROBLEM TO BE SOLVED: To provide a radiator for a vehicle provided with a conduit hardly broken by thermal expansion. SOLUTION: The radiator 1 for the vehicle is provided with: a first tank 11 containing heated cooling water; a second tank 12 containing cooled cooling water; and a core part 20 having conduits 5 each with one end fixed to the first tank 11, and the other end fixed to the second tank 12, and communicating the first tank 11 with the second tank 12. The cooling water contained in the first tank 11 is passed through the conduit 5 of the core part 20, and it carries out cooling while it is being sent to the second tank 12. In the conduit 5, a predetermined side rim part 8, and the other side rim part 9 are formed with different coefficients of thermal expansion in a longitudinal direction, and the conduit 5 bends toward the side with the larger coefficient of thermal expansion during thermal expansion.
