<p><P>PROBLEM TO BE SOLVED: To provide a bag for baseball or softball, which has excellent flying distance performance, while effectively and efficiently reducing a manufacturing cost. <P>SOLUTION: A resin-made projected and recessed sheet 6, whose outer surface is formed in a projected and recessed surface shape, is transferred to the outer peripheral surface of a ball hitting part at the distal end of a bat body 4. The whole area of the bat body 4 or at least an area including the whole surface of the outer surface of the projected and recessed sheet 6 is coated with a resin-made film shape body 7, so that resin-made stereoscopic patterns 8 are formed in the ball hitting part. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
