摘要：
A medical needle extending in a specified direction, wherein the cross sectional area of a vertical cross section cut by a plane perpendicular to the specified direction is regularly increased or decreased depending on a distance from the tip part thereof. The medial needle comprises a plurality of maximum points where the cross sectional area of the vertical cross section is maximized and a plurality of minimum points where the cross sectional area of the vertical cross section is minimized. The cross sectional area of the vertical cross section at the maximum point nearest the tip part is equal to or larger than the cross sectional area of the vertical cross section at the other maximum points. Thus, when the medial needle is pierced in a patient, pain given to the patient can be minimized and damage to the pierced portion of the patient can be minimized.
