To downsize a heat exchanger and to provide a vehicular heat exchange system which can effectively use exhaust heat from a motor.SOLUTION: The heat exchanger is provided in which a first flow passage (second, fourth, and sixth layers) and a third flow passage (first, third, fifth, and seventh layers) are alternately arranged in a stacked direction in a region from a partition wall 56 at one end to a partition wall 55m in the middle, a second flow passage (eighth, tenth, and twelfth layers) and a third flow passage (ninth, eleventh, and thirteenth layers) are alternately arranged in a region from a partition wall 56m in the middle to a partition wall 54 at the other end, and the third flow passage (first, third, fifth, and seventh layers) and the third flow passage (ninth, eleventh, and thirteenth layers) communicate with each other to form a continuous flow passage. The vehicular heat exchange system is also provided that comprises: a first heat exchanger exchanging heat between a first medium for use in cooling of an internal combustion engine and a third medium for use in lubrication of a transmission and/or cooling of a motor; and a second heat exchanger exchanging heat between a second medium for use in cooling of an inverter and the third medium.SELECTED DRAWING: Figure 13
