PURPOSE:To precisely perform positioning of optical parts, parts of precision devides, etc., by putting a plastic adhesives which is not fluid to the contacting surface between a parts to be positioned and an object to be fixed, and by hardening the adhesives after the parts is positioned. CONSTITUTION:A plastic adhesives composed of a powdered filler (e.g. kaoline) and a solventless type adhesive component which can be hardened (e.g. epoxy adhesive) and which has a 70g/cm<2>-20kg/cm<2> yield point and a 10<6>-10<11> poise plastic viscosity at the normal temperature and, moreover, which is not fluid and can be hardened, is put to form a layer between a parts to be positioned and an object to which the parts is fixed. The adhesives is hardened by leaving it as it is after the parts is positioned. In this way, parts can be fixed to objects easily, inexpensively, and firmly with a high accuracy. |
