A plate-type heat exchanger comprises a plurality of plates laminated through gaskets fixed in gasket grooves formed in the entire peripheral edges thereof without using any adhesive agent. The plate-type heat exchanger is characterized in that the liquid-noncontacted peripheral side surface of the gasket body of the gasket is integrally formed with suitably spaced fixing tabs each comprising two or more projecting pieces projecting from the gasket body, and a fixing piece extending parallel with the gasket body and connecting the projecting pieces. The plate is formed with gasket fixing portions associated with the fixing tabs of the gasket for fixing the fixing tabs by force-fitting the fixing pieces of the fixing tabs in slits extending parallel with the gasket groove. Further, the liquid- noncontacted peripheral side surface of the gasket body of the gasket may be integrally formed with suitably spaced L- shaped fixing tabs each comprising a projecting piece projecting from the gasket body and a fixing piece extending parallel with the gasket body and integrally connected to the front end of the projecting piece, the plate being formed with gasket fixing portions associated with the fixing tabs of the gasket for fixing the fixing tabs by force-fitting the fixing pieces of the fixing tabs in slits extending parallel with the gasket groove.
