Abstract
A heat exchanger () includes a flow path layer () in which a first flow path () extending in a first direction and a second flow path () extending in a second direction are disposed in the same layer. In each of the first flow path and the second flow path, a flow path cross-sectional area is reduced and expanded along an extending direction of the flow path. The first flow path and the second flow path intersect each other in the same layer in first portions () of which the flow path cross-sectional area is reduced, due to displacement of the first portions () in a third direction.
