Abstract: A wooden golf club head has an air flow guiding slot structure which comprises an upper guiding port, a lower guiding port, and a continuous wall connecting the upper guiding port and the lower guiding port. The continuous wall is provided with an opening. The upper guiding port is located in a top curved surface of an arcuate side of the head and is provided with a notch. The lower guiding port is located in a bottom inclined surface of the arcuate side of the head. The upper guiding port, the lower guiding port, the opening, and the continuous wall form together an air flow channel for balancing the air flow pressures of the top curved surface and the bottom inclined surface of the head.
