PROBLEM TO BE SOLVED: To provide a check sheet for golf club practices, capable of being used in several times as it is through making the sheet hard to tear even when it is hit with an iron club having a hard hit face made of metal and of being simply, easily and inexpensively manufactured and excellent in storage after being released from the hit face of the club. SOLUTION: The check sheet for the golf club practices keeps the back of a pressure-sensitive marking sheet 10 stuck with the front of a polyester film 20 the front of which is coated with a strong adhesive 201 and the back with a restickable adhesive 202, and the back stuck with a release sheet 30. The film 20 is formed to have a thick of 20-40μm and minutely roughened in the front/back. COPYRIGHT: (C)2008,JPO&INPIT
