Zusammenfassung:A sewing needle is used in a sewing machine. The sewing needle has a working portion with a needle eye and a region which tapers into a needle tip. The needle eye passes through a needle body in a transverse direction perpendicularly to a longitudinal axis of the needle body. A twist groove is recessed in a front face of the needle body relative to the outer contour of the needle body, the twist groove extending in the direction of the needle tip from the needle eye. The twist groove is formed by a thread groove. The twist groove is preferably symmetrical relative to a first longitudinal central plane spanned by the longitudinal axis and the transverse direction. The thread groove has a groove portion adjacent to the needle eye and two end portions, each having a thread groove opening, remote from the needle eye.
