A needle including a needle hole having a changeable form is provided to insert the thread into the hole easily by forming the hole roundly, and to prevent the finger from sliding by forming the needle grooves to the needle body itself. The first end part is formed to be sharp. The second end part is formed to have round cross section. A protrusion is formed at the second end part of the needle body(110). A groove(130) is formed to correspond to the protrusion. A needle hole part(120) is connected with the needle body by coupling the groove with the protrusion. The shape of the needle hole part is changed by the external force, and restored to the original shape under the condition of removing the external force. The protrusion is formed to be a single body with the needle body, and has the T-shape. A coupling hole is formed at the protrusion for connecting the needle body with the needle hole part. A coupling rod is formed at the groove for corresponding to the coupling hole. The needle hole part is formed of silicon. Plural coupling holes and coupling rods are formed at established intervals.
