<p>The invention relates to a medical needle made of a synthetic resin which is reinforced even in the point part and little deforms in puncture even when the needle is one produced by injection molding; and a synthetic resin composition for molding the needle. A needle made of a synthetic resin, produced by molding a composition which comprises a synthetic resin and a reinforcing fiber component consisting of both a fiber having a length of 80µm or below and a fiber having a length exceeding 80µm at a number ratio of the former fiber to the whole fiber component of 40 to 90%. A synthetic resin composition for needles which comprises a synthetic resin and a reinforcing fiber component, prepared by adding at least two kinds of fibers, namely, a fiber having a mean length of 1 to 10mm and a fiber having a mean length of 10 to 100µm to the synthetic resin and kneading the obtained mixture.</p> |
