A ceramics-metal joined body having high temperature characteristics, comprising a ceramics part and a metal part, said body further comprising: a metal deposition layer of one or more metals containing an active metal or metals between said ceramics part and said metal part; and an intermediate layer comprising at least a solder layer between said metal deposition layer and said metal part, wherein said metal deposition layer has been formed by a process comprising one of laminate-deposition and multi-deposition of two or more metals containing an active metal or metals by means of a physical vapor deposition process and heating at a temperature above the melting point of the resultant alloy formed by said metal deposition layer, thereby to perform diffusion to said ceramics part.
