摘要： A head 1 is provided with a head body h1 and an adherend s1. The adherend s1 has a cast resin 53 formed by casting, a metal part 51, and a vibration absorber 55. The cast resin 53 has a formed surface formed by the metal part 51. The cast resin 53 further may have a formed surface formed by the vibration absorber 55. A base material of the cast resin 53 is an epoxy resin, for example. The cast resin 53 may have a cutting surface PL1. The cutting surface PL1 may be a joint surface of the adherend to the head body h1. Preferably, a loss tangent tan δ of the vibration absorber 55 is 0.07 or greater and 0.25 or less.
