PRODUCTION METHOD FOR COPPER/CERAMIC JOINED BODY, PRODUCTION METHOD FOR INSULATED CIRCUIT BOARD, COPPER/CERAMIC JOINED BODY, AND INSULATED CIRCUIT BOARD
A method of producing a copper/ceramic bonded body, the copper member having a composition having a Cu purity of 99.96 mass % or more, a balance of inevitable impurities, a P content of 2 mass ppm or less, and a total content of Pb, Se and Te of 10 mass ppm or less, the method includes bonding the laminated copper member and the ceramic member by pressing and heating, wherein an average crystal grain size of the copper member before bonding is 10 µm or more, an aspect ratio is 2 or less, and a pressing load is 0.05 MPa or more and 1.5 MPa or less, a heating temperature is 800°C or higher and 850°C or lower, and a holding time at the heating temperature is 10 minutes or longer and 90 minutes or shorter.
