A manufacturing method of a gasket adhering to a resin member, the method includes mixing a plurality of liquid materials stored separately and molding the gasket that is made of a mixture of the plurality of liquid materials. The mixture constitutes a liquid silicone-rubber composition that contains a base resin, a crosslinking agent, a curing catalytic agent, a hydrophilic silica filler, and a silane-coupling agent. The hydrophilic silica filler and the silane-coupling agent are contained in different liquid materials before the plurality of liquid materials are mixed.

Manufacturing method of gasket, gasket material molding the gasket for heat exchanger, and heat exchanger

An outer peripheral sealing surface of an inner surface of a core plate of a header tank is configured into a loop and extends along an outer peripheral edge portion of the core plate and clamps a packing in cooperation with an outer peripheral end portion of a tank main body of the header tank. A transition section of the outer peripheral sealing surface connects between a primary section and a secondary section, which are located in two different planes, respectively, and the plane of the secondary section is the same as a plane of a boundary portion sealing surface held between two tube connecting surfaces in the core plate.
