an optical fiber including:
a coating; and
a coating-removed section in which a partial section of the coating is removed from the optical fiber;
a reinforcement member including:
main surfaces; and
a groove formed from one of the main surfaces toward an inside of the reinforcement member, where the groove has a pair of side walls and a bottom wall; and
a resin member that secures the coating-removed section to the pair of side walls and the bottom wall, wherein
a bottom part of the groove that includes the bottom wall has a widthwise cross-sectional shape where the bottom wall constitutes a trapezoidal shape such that a distance between the pair of side walls becomes greater in a direction away from the bottom wall, and
the coating-removed section is apart from the pair of side walls and the bottom wall in a cross section orthogonal to a lengthwise direction of the optical fiber.
