To provide an Al-AlN composite material provided with electric insulation and thermal conductivity, a manufacturing method of the Al-AlN composite material, and a heat exchanger.
Aluminum is melted to flow onto one surface of an AlN plate 2 composed of aluminum nitride and then the melted aluminum is solidified in an inactive gas atmosphere to provide the Al-AlN composite material 1 constituted of mutually joining an Al plate 3 composed of aluminum and the AlN plate 2. The heat exchanger including at least the Al-AlN composite material 1 in a partial portion is configured so that the AlN plate 2 is thermally brought into contact with a heating body. In the manufacturing method of the Al-AlN composite material constituted of mutually joining the Al plate 3 composed of aluminum and the AlN plate 2 composed of aluminum nitride, aluminum is melted to flow onto one surface of the AlN plate 2 and then the melted aluminum is solidified.
