<p>A syringe (1) has a first cut surface (3) formed simply by obliquely cutting a cylinder, and second and third cut surfaces (4, 5) cut so as to form a hill shape which becomes lower in height as the outer diameter side in the left-right cut width direction is approached with respect to the first cut surface (3), wherein the pricking width is further reduced so as to reduce not only skin damage but also the pricking pressure during pricking, thus eliminating the painful prick feeling, and achieving early healing of the prick wound. The outer surface of the cylinder formed with the first, second and third cut surfaces (3, 4, 5) is used as a curved surface (2) which is curved in the needle axis circumference direction and in the axial direction to provide an arcuate outer peripheral edge free from a sharp corner portion which, when pricking, avoids damaging the inner wall of the blood vessel.</p> |
