Optical waveguide member connector and method for producing the same

An optical waveguide member connector comprising:

• an optical waveguide member including an optical waveguide;
• a connector to which the optical waveguide member is attached, the connector having an approximately U shape in cross section;
• and
• an adhesive member making the optical waveguide member adhere to the connector,
• wherein the optical waveguide member includes:
• a bottom surface extending in a first direction orthogonal to a direction in which the optical waveguide extends and a thickness direction, and
• a first side surface and a second side surface that have shapes extending from both first-direction edges of the bottom surface to a thickness-direction first side,
• wherein the connector includes:
• an inner bottom surface having contact with the bottom surface,
• a first inner side surface facing the first side surface across a first gap in the first direction, and
• a second inner side surface facing the second side surface across a second gap in the first direction,
• wherein the first gap is filled with the adhesive member so that the adhesive member has contact with the inner bottom surface facing the first gap, the first inner side surface, and the first side surface, and the second gap is filled with the adhesive member so that the adhesive member has contact with the inner bottom surface facing the second gap, the second inner side surface, and the second side surface,
• wherein a ratio (L1/L0) of a first-direction length L1 of the first gap to a first-direction length L0 of the inner bottom surface, and a ratio (L2/L0) of a first-direction length L2 of the second gap to the first-direction length L0 of the inner bottom surface are 0.01 or more,
• wherein the connector does not include a lid,
• wherein the optical waveguide member further includes:
• a top surface facing the bottom surface in the thickness direction and connecting the thickness-direction first edge of the first side surface to the thickness-direction first edge of the second side surface, and
• wherein the adhesive member has continuous contact with a first-direction first end of the top surface and the first side surface, and has continuous contact with a first-direction second end of the top surface and the second side surface.
