PROBLEM TO BE SOLVED: To provide a metallic spectacles frame of a lighter weight, having ample ornamentability when the spectacle frame has magnesium-base casting parts, aluminum-base casting parts, noble metal casing parts of gold, silver, platinum, etc., titanium-base casting parts or beryllium copper-base casting parts and non-casting parts. SOLUTION: Casting parts and non-casting parts are integrated by casting the magnesium parts or the magnesium alloy parts 14, so as to embed the joint ends of the tough material parts. The metal castings of an aluminum system, a nobel metal system, a titanium system and a beryllium copper system may be used as casting parts. For practical purposes, portions on the front sides, such as a bridge, endpieces, wraparound endpieces and temples, are provided with the casting parts consisting of the metallic materials.
