  The putter club P of this embodiment has the following advantages.

  That is, since the putter club P is composed of the putter head 1, the shaft 2, and the grip 3, the effect of the putter head 1 can be exerted on the putter club P.

  Furthermore, since the putter head 1 is formed in a rectangular shape in plan view, it can have a high moment of inertia.

  Furthermore, since the inside of the putter head 1 has a hollow structure, the shape of the upper surface of the putter head body 10 is formed, and the bottom plate 16 is attached to the bottom surface of the putter head body 10 by welding. -The molding operation can be simplified and the production cost of the putter head 1 can be reduced.

  Furthermore, since the inside of the putter head 1 has a hollow structure, a high moment of inertia can be obtained by dispersing the weight around the periphery of the putter head 1.

  Furthermore, since stainless steel is used as the material for the putter head main body 10 and the bottom plate 16, a putter head having excellent strength and corrosion resistance can be provided.

  Furthermore, since resin is used as the material of the striking surface member 15, the striking surface member 15 becomes lighter than the putter head main body 10, whereby a high moment of inertia can be obtained.

  Further, since the peripheral recesses 11a and 11b are formed on the heel side and the toe side on the rear side of the peripheral portion 11, and the weight members 14a and 14b are disposed here, the peripheral portion 11 can be effectively increased in weight and high. The moment of inertia can be obtained.

  Furthermore, since the weight members 14a and 14b are attached by welding, the assembling work can be simplified and the manufacturing cost of the putter head 1 can be reduced.

  Further, since tungsten having a higher specific gravity than the putter head main body 10 is adopted as the material of the weight members 14a and 14b, the peripheral edge 11 can be effectively made heavy and a high moment of inertia can be obtained.

  Further, since the concave portion 12 is colored black and the peripheral edge portion 11 is subjected to black nickel finish (black nickel plating), the concave portion 12 is easily recognized as a putter head by separating from the peripheral edge portion 11, and the golfer is more mallet-type. It can be visually recognized as a putter head shape.

  Furthermore, since the linear marking line 12a is formed in the concave portion 12 from the striking surface side toward the rear, and the marking line 12a is colored white, the golf ball can be accurately applied to the striking surface member 14.

  Next, a second embodiment of the present invention will be described below with reference to FIG.
