Abstract

An optical device includes a semiconductor element configured to emit emission light or to receive incident light, including a first fitting part including a portion having a convex shape in a first region; an optical member arranged on an optical path of the emission light emitted from the semiconductor element or the incident light entering the semiconductor element, including a second fitting part fitted to at least a part of the portion having the convex shape, the first region being opposed to the optical member; and a joint part that joins the semiconductor element and the optical member, arranged between the first fitting part and the second fitting part.
