摘要

PROBLEM TO BE SOLVED: To provide methods of manufacturing an opto-electric hybrid board and an opto-electric hybrid module, which include an inspection step of allowing accurate and efficient measurement of a position of an optical waveguide, and to provide an opto-electric hybrid board and an opto-electric hybrid module which are obtained by these methods.;SOLUTION: The method of manufacturing an opto-electric hybrid board, the method of manufacturing an opto-electric hybrid module by the method of manufacturing an opto-electric hybrid board, and the opto-electric hybrid board and the opto-electric hybrid module manufactured by these methods are provided. The method of manufacturing an opto-electric hybrid board includes: a step (A) of patterning a dummy core together with a core pattern on one surface of a substrate having a lower clad formed thereon; a step (B) of forming a reflecting mirror on the core pattern and the dummy core; a step (C) of patterning, on the other surface of the substrate, a light shielding pattern in the vicinity of a projection region on which reflected light from the dummy core is projected by the reflecting mirror, together with an electrode pattern; and a step (D) of measuring an amount of displacement between the core pattern and the electrode pattern on the basis of the total amount of luminance of reflected light from the dummy core, which passes without being shielded.;COPYRIGHT: (C)2012,JPO&INPIT
