Summary:PURPOSE: To provide a waveguide type module which is connectable to optical parts, such as optical connectors, with low connection loss and a process for producing this module. CONSTITUTION: Fitting guide grooves 8 extended in the longitudinal direction of optical waveguides 5 are formed on both sides across the optical waveguide forming region of a waveguide chip 15 produced by forming the optical waveguides 5 on a substrate 4. Positioning and fitting pins 6 for connection of the waveguide chip 15 are fixed into these fitting guide grooves 8 and the connecting end face 13 side of the waveguide chip 15 is provided with an upper protective plate 20 consisting of 'Pyrex (R)' glass covering at least the waveguide forming region without contact with these positioning and fitting pins 6, by which the waveguide module 1 is formed. Production of the waveguide type module 1 is executed by fixing the upper protective plate 20 onto the waveguide chip 15 and polishing the connecting end face 14 of the upper protective plate 20 and the connecting end face 13 of the waveguide chip 15 in such a manner that both connecting end faces 14, 13 are made flush with each other, then fitting and fixing the positioning and fitting pins 6 into the fitting guide grooves 8.
