PURPOSE:To adjust easily an optical axis and to execute sticking with a stable optical coupling degree by providing a recessed groove which a projecting part of desired number of optical transmission line parts being parallel to the optical axis is inserted through, and a recessed groove which a projecting part of optical function parts crosses the optical axis at a desired angle and inserted through, on a substrate. CONSTITUTION:Optical transmission line parts 14 are inserted into an axial core hole of housings 15a-15c consisting of a rectangular parallelepiped-shape glass of the same shape. Square-shaped projecting parts 16a-16c are formed in parallel to the axial core hole on the lower face of the housings 15a-15c. An optical filter element 10a is stuck to one side face opposed to a function parts body 18 consisting of a rectangular parallelepiped-shaped optical glass of optical function parts 17, and an optical filter element 10b is stuck to a position shifted in parallel to the element 10a on the other side face. On the lower face of the body 18, a square-shaped projecting part 19 is formed in parallel to the side face to which the element 10a has been stuck. Parallel recessed grooves 12a, 12b, and a recessed groove 13 crossing said grooves at a prescribed angle are formed on the upper face of a substrate 11. In this way, the optical axis of the parts 14, 17 is adjusted easily, and sticking is executed with a stable optical coupling degree. |
