Abstract
The present invention intends to prevent deviation and gap from being generated in a joining section of a golf club in which a head main body 10A and a surface material 10B are integrated by joining together and provide a high quality golf club head having an improved durability and manufacturing method thereof. In the golf club head in which the head main body 10A and the surface material 10B are joined together such that they are integral, a groove 18 is provided in a joining section between the both members and joint material 19 composed of fiber reinforced resin material is embedded in that groove. Consequently, the joining strength is intensified.
