    Abstract: A cutting jig includes a fixing member for inserting a distal end portion of an optical fiber, and an inclination cutting unit movable with respect to the fixing member for cutting the distal end portion. The distal end portion is defined into a proximal end portion and a free end portion. The inclination cutting unit includes a one end edge of a closing plate and a blade portion incapable of relative movement to each other. The inclination cutting unit can perform a first movement and a second movement that is a greater movement amount than the first movement. The one end edge is brought into contact with the free end portion based on the first movement, and the free end portion moves to be inclined with respect to an extension line EL. A blade edge is brought into contact with the free end portion based on the second movement.

    Abstract: An opto-electric hybrid board is capable of being mounted on a connector having a bottom wall. The opto-electric hybrid board sequentially includes an optical waveguide and an electric circuit board toward one side in a thickness direction of these. The optical waveguide includes an under clad layer, a core layer disposed on a one-side surface of the tinder clad layer, and an over clad layer disposed on the one-side surface of the under clad layer so as to cover the core layer. The under clad layer is in contact with an other-side surface in the thickness direction of the electric circuit board. The one-side surface in the thickness direction of the electric circuit board is capable of being placed on the bottom wall.

    Abstract: An optical waveguide member connector kit includes an optical waveguide member including an optical waveguide and a connector accommodating the optical waveguide member. The connector includes a main body having a bottom wall, and a first wall and a second wall that extend from the bottom wall toward one side in a thickness direction of the bottom wall and face each other at spaced intervals therebetween, and a lid disposed between the first wall and the second wall and sandwiching the optical waveguide member with the bottom wall when the optical waveguide member is accommodated in the connector. A ratio (L1/L2) of a length L1 in a facing direction of the lid to a facing length L2 between the first wall and the second wall is 0.80 or more and 0.99 or less.

    Abstract: An opto-electric hybrid board includes an optical waveguide and an electric circuit board. The opto-electric hybrid board has an electrode at one end portion in a first direction perpendicular to the thickness direction, and optically and electrically connects an optical element emitting light from a space between the one end portion and the other end portion. The electric circuit board includes a terminal portion electrically connected to the electrode and a support portion that supports the other end portion. The optical waveguide includes a light receiving portion for receiving light emitted from the optical element, which is positioned between the terminal portion and the support portion, when projected in the thickness direction, and a one-side surface in the thickness direction of the terminal portion is positioned at the other side in the thickness direction with respect to a one-side surface in the thickness direction of the support portion.

    Abstract: An optical waveguide member connector kit includes an optical waveguide member including an optical waveguide and a connector having an accommodation space that is capable of accommodating the optical waveguide member. When the optical waveguide member is accommodated in the accommodation space, the connector has an opening portion reaching the optical waveguide member from the outside of the connector and when the optical waveguide member is accommodated in the accommodation space, at least one of the optical waveguide member and the connector includes a groove communicating with the opening portion facing at least the other side of the optical waveguide member and the connector.

    Abstract: An opto-electric hybrid module is provided which has a linear light-path core and an electric circuit including mounting pads and an electric circuit body provided on a surface of an under-cladding layer of an optical waveguide. An optical element is mounted with its electrodes in abutment against the mounting pads. The electric circuit body and a portion of the surface of the under-cladding layer other than a core formation portion and an electric circuit formation portion are covered with a stack including a core material layer and an over-cladding material layer. A surface portion of the stack present between the mounting pads and the electric circuit body is located at a lower height position than a surface portion of the stack present on the electric circuit body.
