Abstract
An optical connection device according to the invention is an optical connection device for optically coupling light propagated through an optical waveguide to an optical element arranged outside the optical waveguide and with the following configuration. Part of the optical waveguide is removed so as to be shaped like a groove. The optical waveguide and the optical element are arranged so that an optical axis of the optical waveguide intersects an optical axis of the optical element at a specified angle inside the groove. An optical unit is arranged at a position of intersection of the optical axes for turning light by reflection from one optical axis along the other optical axis.
