a second member formed of a fiber reinforced resin, wherein;
the first member and the metal plate are apart from each other; and
the second member joins the first member with the metal plate;
wherein the metal plate is made of a metal material, which is larger in specific gravity than the metal material of the first member; and
wherein a portion of the second member between the first member and the metal plate recesses from the metal plate and a bottom surface of the first member;
wherein a gap is defined by the recessed portion of the second member between the first member and the metal plate,wherein an average width of the gap is between 4 mm to 12 mm, andwherein a depth of the gap is between 0.7 mm to 1.5 mm.

The front body has a face portion, a metal sole portion, a metal side portion (toe), a metal crown portion, a metal side portion (heel), and a hosel portion. A slight gap in a range of 4 mm to 12 mm is formed between a front side of the sole plate and the metal sole portion. This part is formed of the FRP body. Preferably, the metal material of the front body includes a titanium-based alloy or a zirconium-based amorphous alloy. The sole plate is made of stainless steel.
