To obtain a high bullet resisting performance by effectively propagating and dispersing a stress upon arrival of the bullet in the direction of thickness.
A bullet resisting pad 3 is composed of the three dimensional fabric of wholly aromatic aramid fibers or super high molecular weight polyethylene fibers. A first group of fibers parallel to a protective surface 3a is formed with X yarns 4 (warp) and Y yarns 5 (waft) perpendicular mutually. Z yarns 6 pass through in a zigzag manner all the spaces surrounded by the X yarns 4 and the Y yarns 5 and extend vertically to the protective surface 3a. Accordingly, a stress upon arrival of a bullet is propagated not only to the X yarns 4 and the Y yarns 5, but also in the direction of thickness through the Z yarns 6, so that the stress can be dispersed.
