There are provided a bonded member comprising different materials which are bonded together, the bonded member having air tightness at the interface between the bonded materials and also having thermal cycle properties and thermal shock properties and being able to be produced by a simple operation, and an easy-to-practice production method of the bonded member comprising different materials. The bonded member comprising different materials is a bonded member comprising a ceramic base material 1 and a metallic member 7 which are bonded together, wherein a solder material 5 comprising Au is disposed on the surface of the ceramic base material 1 via an active metal layer, the active metal layer and the solder material 5 are molten by heating so as to form a precoat layer 6, the metallic member 7 is disposed on the surface of the precoat layer 6 via an insertion metal layer comprising pure metal which may form an alloy having a lower melting point than Au with Au or an alloy of the pure metal and Au, and the insertion metal layer and at least a portion in the vicinity of the interface between the insertion metal layer and the precoat layer 6 are molten by heating to bond the metallic member 7 and the precoat layer 6 together so as to bond the ceramic base material 1 and the metallic member 7 together.
