Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a golf club head, wherein an adherend which is bonded with a double-coated adhesive tape is hard to come off. SOLUTION: The head includes a head body h1, the double-coated adhesive tape t1, and the adherend s1 which is bonded to the head body h1 by the double-coated adhesive tape t1. The double-coated adhesive tape t1 has a first adhesive layer 30 which is installed on the innermost layer, a second adhesive layer 36 which is installed on the outermost layer, and intermediate layers 32 and 34 which are installed between the first adhesive layer 30 and the second adhesive layer 36. The intermediate layers include a non-woven fabric layer 34 and/or a resin layer 32. The resin layer 32 does not include air bubbles. Preferably, the double-coated adhesive tape has a five-layer structure in which the first adhesive layer, the resin layer without air bubbles, the non-woven fabric layer, the resin layer without air bubbles, and the second adhesive layer are laminated in this order.
