There is disclosed a heat exchanger capable of suppressing the increase of a pressure drop while improving a non-uniform rate distribution of a fluid. A heat exchanger T of the present invention is constituted of flat plates 1, 2 each having an inflow port 15 of the fluid on one end thereof and an outflow port 16 of the fluid on the other end, and offset type fins 5 provided in the flat plates 1, 2, and includes a fin orthogonal region H where the plate fins 5 cross the flow direction of the fluid from the inflow port 15 to the outflow port 16 at right angles and a fin parallel region V where the plate fins 5 are disposed in parallel with the flow direction of the fluid from the inflow port 15 to the outflow port 16, the fin orthogonal regions H are provided on the sides of the inflow port 15 and the outflow port 16, and the fin parallel region V is provided between the respective fin orthogonal regions H.
