Abstract:
1. An optical device comprising: a light guide member that guides light; a first holding member that holds the light guide member; an optical element that functions by the light guided by the light guide member being irradiated; a second holding member that holds the optical element; and an optically coupled member elastically deformable in a diameter direction by an end portion of the first holding member and an end portion of the second holding member being inserted into opposite ends of the optically coupled member, wherein the optically coupled member presses both the first holding member and the second holding member in the diameter direction of the optically coupled member to optically align the light guide member relative to the optical element in the diameter direction, a face at the end portion of the first holding member is on a same plane as a face of an end of the light guide member inserted into the first holding member; and a face at the end portion of the second holding member is on a same plane as a face of an end of the optical element inserted into the second holding member.
