In a puncture needle for an endoscope, in a state in which a distal end of an outer sheath (71) is located in an observation field of an observation optical system of an endoscope and a needle slider (23) is retracted to abut a needle slider engaging section (9b), a distal end of an inner sheath (74) is located closer to a distal side than a proximal end (108b) of a raising base (108) in the outer sheath (71), and a proximal end of the inner sheath (74) is located closer to a proximal side than a needle tip (3a) of a needle tube (3) in the outer sheath (71).
