Abstract
A puncture needle for an endoscope includes: a flexible sheath; a needle component that is placed on an interior side of the sheath such that it can move freely forwards and backwards; a wire that is provided at a base end portion of the needle component, and that moves the needle component forwards or backwards along an axial direction of the sheath; and an operating section that is connected to an operating side of the sheath, and operates the wire. This wire is formed by a metal material that has elasticity, and a bent portion is provided in the wire that generates friction against an inner wall of the operating section, and imparts resistance to the forwards and backwards movement of the needle component.
