    Abstract: A heat exchange device includes a heat exchange main body portion, a joint member, and a resin sealing portion. The heat exchange main body portion has an internal flow path through which a heat exchange medium flows, and a metal wall portion including a through-hole communicating with the internal flow path. The joint member has a protruding portion and a hollow portion. The protruding portion includes an opening through which the heat exchange medium is supplied or discharged. The protruding portion protrudes toward an outside of the heat exchange main body portion through the through-hole. The hollow portion is formed for causing the opening and the internal flow path to communicate with each other. The resin sealing portion seals a gap between an inner peripheral surface of the through-hole and an outer peripheral surface of the protruding portion.
