LAYERED BODY AND MANUFACTURING METHOD FOR LAYERED BODY

摘要

When a laminated body having a metal film formed on a ceramic base member is manufactured by using a cold spraying method, a laminated body having a high adhesion strength between a ceramic and the metal film and a method of manufacturing such a laminated body are provided. The laminated body includes a ceramic base member 10 having an insulating property, an intermediate layer 50 including metal or alloy as a main component formed on a surface of the ceramic base member 10, and a metal film layer (a circuit layer 20 and a cooling fin 40) formed on a surface of the intermediate layer 50 by accelerating a powder of metal or alloy with a gas and spraying and depositing the powder on the surface of the intermediate layer 50 as the powder is in a solid state.
