PURPOSE: A structure of a needle for an ultrasonic guided procedure is provided to enable a user to accurately insert a needle into a site to be treated. CONSTITUTION: A structure of a needle for an ultrasonic guided procedure comprises a syringe needle hole, an ultrasonic wave reflection surface, an ultrasonic wave passing surface(103), and an ultrasonic wave reflection groove(101). The syringe needle hole(106) has a transverse section of a reverse tunnel type. In the ultrasonic wave reflection side, two inclination angles are adjacent towards a slanting surface(100a). The ultrasonic wave reflection groove is formed in a polygonal shape of a constant depth.
