A heat-transmitting plate member has a pair of heat-transmitting plates. Each of the plates is made from a resin material. The heat-transmitting plate member has an inner passage through which inner fluid flows and a tank portion communicating with the inner passage. The tank portion has a thickness thicker than that of a portion corresponding to the inner passage in the heat-transmitting plate member, so that desired heat-exchange characteristic at the inner passage can be obtained while desired ability to withstand pressure at the tank portion is obtained.
