Abstract
In a light irradiating device of a scanning endoscopic device, a proximal end of a lens optical system is located apart from a distal end of an optical fiber in directions parallel to the longitudinal axis, and a lens-side facing portion faces a fiber-side facing portion apart from the fiber-side facing portion by a second dimension smaller than a first dimension between the distal end of the optical fiber and the proximal end of the lens optical system in the directions parallel to the longitudinal axis. The proximal end of the lens optical system and the distal end of the optical fiber are located between a distal end and a proximal end of the window in the directions parallel to the longitudinal axis.
