In a plate type heat exchanger formed by laminating a plurality of plates (11), in each of which a resin-wrapped gasket (15) obtained by enclosing a liquid contacting surface of a core (15a) of an elastic material with a resin cover (15b) of a high corrosion resistance is set in a gasket groove (13) surrounding the circumference of a heating surface (12), a fixing member (16) is formed integrally with and on the portion opposite to the liquid-contacting side of the core (15a), and a hole-carrying recess (14) engageable with the fixing member (16) in an outer circumferential portion of the plate (11), whereby the resin-wrapped gasket (15) can be set in the gasket groove (13) in the plate (11) without using a bonding agent.
