16. A golf club head comprising:
a face plate comprising a plate front surface constituting a club face at least partially, a plate rear surface opposite the plate front surface and having an outer peripheral portion, and a plate side surface extending between the plate front surface and the plate rear surface; and
a head main body being provided with an opening to receive the face plate and a receiving surface formed around a periphery of the opening to support the outer peripheral portion of the plate rear surface, wherein
the receiving surface is formed with a partially interrupted discontinuity so that the outer peripheral portion has a non-supported region that is not directly supported by the head main body,
a portion of the plate side surface corresponding to the non-supported region is not directly supported by the head main body,
the face plate is fixed to the head main body by a plastic deformation portion of the head main body, and
a first gap is formed between the non-supported region and the head main body with a distance in a direction orthogonal to the club face,
the head main body comprises an extension that is formed so as to face a portion of the plate side surface corresponding to the non-supported region of the face plate such that a second gap is formed between the extension and the portion of the plate side surface of the non-supported region in a vertical direction,
the second gap is in communication with the first gap, wherein
a filling member is arranged in at least a part of the first gap and/or second gap, and wherein
a specific gravity of the filling member is larger than specific gravities of the face plate and the head main body.
