Abstract: The present invention provides a method of manufacturing a golf ball having a solid core formed of a rubber composition and a cover of at least one layer encasing the core, which method includes the steps of treating a surface of the core with a solution containing a halogenated isocyanuric acid and/or a metal salt thereof, and covering the treated core with a cover material. The invention also provides a golf ball obtained by such a method. Golf balls obtained by this method have a good feel and a good scuff resistance, and also have a high durability to impact.

Abstract: There are provided a golf ball molding die in which a mold deposit produced when a gas is discharged can be removed easily, and the area of a venting opening per unit area of the tip end of a pin can be increased tremendously, and a golf ball manufactured by using the golf ball molding die. A golf ball molding die in accordance with the present invention includes at least two die bodies which are configured so that a cavity for forming a golf ball is formed by joining the die bodies to each other; a venting hole which is provided in at least one of the die bodies to discharge a gas in the cavity; and a pin which is present in the venting hole, the pin being configured so that a plurality of layers are lapped on each other from the center thereof.
