1. An iron type golf club head comprising:
- a head main body;
a face plate fixed to a front surface side of said head main body to form a face surface;
a cavity portion formed in said head main body, said cavity portion open to the front surface side; and
a plurality of viscoelastic bodies disposed within said cavity portion,wherein said plurality of viscoelastic bodies are made of viscoelastic materials with loss coefficients the temperature dependences of which are different,wherein said plurality of viscoelastic bodies are arranged along a rear surface of said face plate, andwherein each viscoelastic body is in tight contact with the rear surface of said face plate.
