PROBLEM TO BE SOLVED: To provide a golf club for practice, which can make users easily perceive the positions and angles of heads and shafts with their hands in backswing or follow swing when practicing golf swings while enabling them to practice swing grips intellectually with thumbs and index fingers of hands in dominant arms and with little fingers of hands in non-dominant arms. SOLUTION: The golf club for practice is made up of a grip part 30, a shaft part 20 and a head part 10. Pressure sensors 34 and 35 are installed respectively at a position on the tip side of the grip part 30, where it is held with the roots of index fingers and thumbs of hands in dominant arms and/or at a position on the base end side of the grip part 30, where it is held with little fingers of hands in non-dominant arms and detects forces when the grip part is gripped. Electric vibrators 11 and 12 are built into the head part 10 and starts vibrations by the vibrators 11 and 12 when the pressure sensors 34 and 35 detect pressures exceeding a prescribed value.
