Abstract
The optical circuit board includes a wiring board including a plurality of laminated insulating layers, and a wiring conductor disposed between the insulating layers; an optical waveguide including a lower clad layer, an upper clad layer and a core sandwiched between the lower clad layer and the upper clad layer, disposed on an upper surface of the wiring board, and extending in one direction; a reflection surface including an inner surface of a groove formed in a part of the core of the optical waveguide, and being perpendicular to an extending direction in a plane view and having a predetermined angle with respect to the upper surface in a cross sectional view; and a metal layer disposed on an upper surface of the insulating layer on the upper side than the wiring conductor of the wiring board, and set as a bottom surface of the groove.
