PROBLEM TO BE SOLVED: To provide a plate-type heat exchanger capable of suppressing increase in fluid pressure loss, even if an angleθ, between the centerline in the longitudinal direction of a heat transfer plate and a corrugated part, is increased in the plate-type heat exchanger. SOLUTION: In the plate-type heat exchanger 100, a plurality of heat transfer plates 2 and a plurality of heat transfer plates 3 are laminated alternately. Between the laminated heat transfer plates 2, 3, first flow passages where first fluid is made to flow and second flow passages where second fluid is made to flow are formed alternately, in the laminating direction so that the first fluid and second fluid exchange heat via the heat transfer plates 2, 3. In the heat transfer plates 2 and in the heat transfer plates 3, the corrugated parts 11a, 12a having a corrugated shape in which projections and recesses are alternately juxtaposed are formed, respectively. The projection 31 of the heat transfer plate 2 and the projection 32 of the heat transfer plate 3 are made to intersect with each other and abut against each other at an intersecting part 60. In an abutting part of the projection 32a of the heat transfer plate 2, a projecting part 13, which abuts against the projection 31a of the heat transfer plate 3 in the intersecting part 60, is formed.
