ABSTRACT:
A sewing machine needle capable of preventing stitch skipping and fabric yarn breakage, irrespective of high-speed and multifunction sewing machines and diversified materials being used. Over a predetermined length from an edge, closer to a needle point, of a needle eye toward the needle point, a blade has a straight profile extending parallel to a longitudinal axis of the needle as viewed from a side of the needle in a direction orthogonal to a direction in which the needle eye extends. Over a predetermined length from the straight profile portion toward the needle point, the profile of the blade is a flat cross-section in which the thickness thereof in the direction in which the needle eye extends is larger than the width thereof in the direction orthogonal to the direction in which the needle eye extends. In a needle point portion following the flat cross-section portion and extending to the needle point, the blade has a sectional shape of a perfect circle.
