<p>A flange portion (2) arranged on the distal end (7) of a syringe body (1) has a flat, skin-contacting surface (9) which contacts the skin of the subject (S), and on this skin-contacting surface (9), at least one recessed portion (10) is formed in a shape extending from near the injection needle (3) to the outer edge of the flange portion (2) and widening away from the injection needle (3) so that pressure from the skin-contacting surface (9) dissipates outwards.</p> |
