Abstract: A wood-type golf club head includes a body and a crown plate. The body includes a striking face and a crown. An opening is defined in the crown of the body. The crown further includes an engaging section between a front edge delimiting the opening and a top end of the striking face. The crown plate is bonded to the crown of the body and covers the opening of the body.
