Zusammenfassung:	A structure of a drawn cup-type heat exchanger of improved pressure tightness is provided. A drawn cup-type heat exchanger is configured by stacking in plural number a long and thin tube element containing an inner fin inside a pair of cup plates. The cup plates have a flat containing portion containing the inner fin and a pair of cup portions communicating with both end portions of the containing portion; a circulation hole for communicating fluid into each of tube elements to be stacked is formed in the cup portions; and, to position both end portions in a longitudinal direction of the inner fin to be contained in front of the circulation hole of the cup portions, a corner portion is formed at at least one end portion in a width direction at both extremities in a longitudinal direction of the containing portion.
