    摘要: An optical device includes: a lens member including a plurality of lenses arranged such that optical axes of the lenses are substantially parallel to one another; and a plurality of column parts that are each provided along the optical axis of each lens among the plurality of lenses and each allow light to pass through inside, each column part having an outer periphery through which light is less likely to pass from inside to outside the column part than through an end portion of the column part in a direction along the optical axis, the plurality of column parts being integrally formed and disposed to face the lens member.
