1. An optical connector module comprising:
an optical waveguide board; and
an optical connector attached to the optical waveguide board,
wherein the optical connector includes
a positioning target portion that engages with the optical waveguide board, and
the optical connector is positioned relative to the optical waveguide board in a state in which the positioning target portion is engaged with the optical waveguide board,
wherein the optical waveguide board includes
an optical waveguide including a first cladding and a core stacked on the first cladding,
the first cladding being stacked on a substrate in a stacking direction perpendicular to the substrate, and
a positioning core that is stacked on the first cladding by using a material the same as a material of the core and that engages with the positioning target portion,
wherein the positioning core protrudes further than the core toward a side opposite to the substrate in the stacking direction,
wherein a section of the positioning target portion is semicircular, and
wherein the positioning core includes:
a small-width portion accommodated in the positioning target portion in planar view,
a large-width portion located outside the positioning target portion in planar view and having a larger width than the small-width portion, and
an engagement portion that is continuously formed so as to gradually become wider from the small-width portion toward the large-width portion and contact an end Portion of the positioning target portion.
