Abstract
Mechanical strength of a lens that optically couples an optical waveguide and an optical fiber provided on a substrate is improved. A lens unit that optically couples an optical waveguide provided on a substrate and an optical fiber has a lens portion and a holding portion that holds the lens portion, and the holding portion has a thick portion, along one side surface that is not a surface through which an optical axis passes, in which a thickness measured in a direction of the optical axis is larger than a thickness of an other portion of the holding portion.
