Abstract

PURPOSE:To obtain an insertion hole with high concentricity at a chip, by adhering a quite thin chip having a large number of porous parts at the tip of a ferrule made of ceramic, etc., in which an inner hole remains as sintered, and using a master with the high concentricity. CONSTITUTION:High circularity is attached on the outer peripheral plane 2 of the ferrule 1 made of ceramic, and the inner hole 3 remains as sintered.The chip 4 is adhered on the inner hole 3. The chip 4 is provided with quite thin thickness, and a large number of micro porous parts to facilitate working are provided in its center part 51 structurally. It is advisable that the size of the porous part is decided at around 0.2mum. A piercing process can be promoted moreover by filling a material to promote optical and chemical reaction on the porous part 51. The master whose outer periphery and piercing part are provided with precise concentricity is used to find the piercing part, and the working is performed setting the concentricity as reference. In such a way, it is possible to obtain the insertion hole with the precise concentricity.
