The invention claimed is: 1. A hollow golf club head comprising a head main body made of a metallic material and having a bottom portion provided with a recess, the bottom portion recess comprising a toe-side primary portion, a heel-side primary portion, and a secondary portion provided between the heel-side portion and the toe-side portion, wherein the height of the toe-side primary portion and the height of the heel-side primary portion are both greater than the height of the secondary portion, and wherein the secondary portion has a thickness larger than those of the toe-side primary portion and the heel-side primary portion, and at least one weight member having a specific gravity larger than that of said head main body, said weight member comprising a first weight member attached to the toe-side primary portion of said bottom portion recess and a second weight member attached to the heel-side primary portion of said bottom portion recess. 2. The golf club head according to claim 1 , wherein the recess has a thickness smaller than that of the remainder of the bottom portion around the recess. 3. The golf club head according to claim 1 , wherein the bottom portion recess has a thickness in a range of from 0.5 to 2.0 mm. 4. The golf club head according to claim 1 , wherein the difference between thicknesses of the recess and the remainder of the bottom portion around the recess is in a range of not less than 0.1 mm. 5. The golf club head according to claim 1 , wherein the recess has a longitudinal width along the front-back direction of the head, wherein the longitudinal width gradually enlarges toward a heel side and a toe side from its center. 6. The golf club head according to claim 1 , wherein the toe-side primary portion and the secondary portion are smoothly connected to one another, and the heel-side primary portion and the secondary portion are smoothly connected to one another. 7. A hollow golf club head comprising a head main body made of a metallic material and having a bottom portion provided with a recess, the bottom portion recess comprising a toe-side primary portion, a heel-side primary portion, and a secondary portion provided between the heel-side portion and the toe-side portion, wherein the height of the toe-side primary portion and the height of the heel-side primary portion are both greater than the height of the secondary portion, and wherein the secondary portion has a thickness smaller than that of the remainder of the bottom portion around the recess, and at least one weight member having a specific gravity larger than that of said head main body, said weight member comprising a first weight member attached to the toe-side primary portion of said bottom portion recess and a second weight member attached to the heel-side primary portion of said bottom portion recess.
