摘要：

PURPOSE:To highly accurately position and assemble an optical component by etching a photosensitive glass substrate, and forming a cross-section, and making an optical unit abut on the section and positioning it. CONSTITUTION:The photosensitive glass substrate 5 is exposed and treated thermally and the part of polycrystalline composition shown by a dotted line is etched in its thickness direction and removed completely to form the section A and section B. The optical unit 2 where, for example, a light emitting element, a light receiving element, an optical fiber, etc., are mounted is positioned by abutting on the sections A and B. Consequently, the optical unit 2 is positioned in the X and Z directions with the sections A and B and mounted on a flat substrate 1, so the unit is positioned in the Y direction. Thus, the unit is positioned in the three directions, so the arrangement and assembly with high-accuracy is made possible.
