To solve the following problem: putter angle adjustment is effective since a smooth swing can be performed and a probability of cup-in increases when an angle of a putter is set to an appropriate angle suited to an individual form, however it is needed to bend a neck part in order to adjust an angle of the putter, and work therefor is performed by a technician using a special tool and takes costs.

There is provided a putter, the angle of which can be easily adjusted by screwing by a user himself/herself at any time.
