Abstract
A metal fiber for fiber reinforced concrete includes a linear main body that extends in an X-Y plane, having width in a Y direction, a length in an X direction, and a thickness in a Z direction within a three dimensional space defined by X, Y, and Z axes which are perpendicular to each other. Ends of the linear main body are bent portions which are bent at an obtuse angle in the Z direction. An elongate metal plate is intermittently conveyed in the Y direction on a die of a pressing machine at a pitch corresponding to the width of the metal fiber in the Y direction. The leading end of the metal plate is sheared to cut out and produce the metal fiber.
