Abstract

See full text

A method for producing a ceramic circuit board including a ceramic substrate and a metal circuit formed on the ceramic substrate. The disclosed method includes a step of forming the first metal layer in contact with the ceramic substrate by spraying a first metal powder containing at least either of aluminum particles or aluminum alloy particles together with an inert gas onto a surface of a ceramic substrate from a nozzle, in which the first metal powder is heated to from 10° C. to 270° C. and then ejected from the nozzle 10 and a gauge pressure of the inert gas at an inlet of the nozzle 10 is from 1.5 to 5.0 MPa, a step of subjecting the first metal layer to a heat treatment in an inert gas atmosphere, and the like.
