To provide a light for a sewing machine capable of illuminating the needle location position and the periphery of the sewing machine, the hand part (bosom) of an operator and a sewing part of an object to be sewn, etc., to lightness suitable for sewing work in the sewing work.

After fixing a fixing part 30 of the light 10 for the sewing machine to the arm part Aa of the sewing machine A by a magnet 31, the spherical member 41 or the like and cylindrical member 42 or the like of a supporting part 40 are turned and bent, and an illumination part 20 is variably adjusted to the direction and angle of emitting light toward the needle location position and the periphery of the sewing machine A. Also, the light emitted from the cold cathode tube 21 of the illumination part 20 and the light reflected by a reflector 23 are converged to a visual field angle by a converging sheet 22 and roughly equally emitted toward the hand part (bosom) of the operator and the sewing part of the object to be sewn with the needle location position of the sewing machine A as a center, and illumination for clearly viewing the needle location position of the sewing machine A, the hand part (bosom) of the operator and the sewing part of the object to be sewn with the eyes of the operator is obtained.
