PURPOSE:To provide an optical circuit part capable of dividing a light into a light having a required wavelength and composing the light having the required wavelength. CONSTITUTION:A first filter 1 and a second filter 2 are stuck to a glass bock 12 having an apex angle alpha, and the first light receiving surface 3 of the first filter 1 is opposed to the second light receiving surface 4 of the second filter 2 to form an optical circuit part 5 for reflecting a light between the first and second light receiving surfaces 3, 4. On the base part side of the optical circuit part 5, an incident side optical fiber 10a is provided through a collimator lens 11a, and on the back surface 6 side of the fist filter 1 corresponding to each position 16-19 in which the light incident from the optical fiber 10a to the optical circuit part 5 is advanced between the first and second light receiving surfaces 3, 4, and incident to the first light receiving surface 3, each optical fiber 10b-10e on emitting side is arranged through collimator lenses 11b-11e. |
