9. An optical connection structure comprising:
a Si waveguide coupled to an optical fiber, the Si waveguide and the optical fiber having different mode fields;
an optical body in a propagation path of light between the Si waveguide and the optical fiber and configured to change a course of radiation mode light emitted from the Si waveguide and propagating in a direction away from an optical axis thereof to obtain waveguide mode light passing through the optical body;
a bridge body bridging the Si waveguide and the optical fiber; and
a support coupled to the bridge body and configured to support the optical body, wherein the support includes a first support and a second support facing each other along the optical axis of the optical body, first end parts of the first support and the second support are joined to the optical body, and second end parts of the first support and the second support are joined to the bridge body.
