Abstract
A light-irradiation-device delivery apparatus includes: a metal needle tube having a longitudinal axis, a side hole, which penetrates from an inner circumferential surface to an outer circumferential surface, and a blade surface at a distal end thereof; an optical fiber that is accommodated inside the needle tube, the optical fiber including a core allowing light to propagate, a clad covering an outer circumferential surface of the core, and an emission area provided at a distal-end section of the optical fiber; and a positioning member that positions the emission area between a distal end and a proximal end of the needle tube in the longitudinal-axis direction. The distal end of the optical fiber is positioned in an interior space of the needle tube in a state where the emission area is positioned between the distal end and the proximal end of the side hole.
