Iron golf club head

An iron golf club head comprising:

• a club face provided with score lines,
• a top extending backward of the club head from an upper edge of the club face,
• a sole extending backward of the club head from a lower edge of the club face, and
• a hosel disposed in a heel side of the club head and provided with a shaft inserting hole,
• wherein
• the depth of the center of gravity of the club head is 5.5 mm or more,
• wherein
• in a standard state of the club head in which the club head is set on a horizontal plane such that the score lines become horizontal and the central axis of the club shaft inserting hole lies within a vertical plane,
• the club head satisfies the following condition (1) in the cross section of the club head taken orthogonally to the above-said vertical plane at any position within a range in the toe-heel direction of the club head which range is defined between the position of the heel-side most end of the score lines and the position at which the height of the club face becomes maximum:
• (1) the horizontal distance A from the lower edge of the club face to the position of a backmost end of the club head on the sole-side is not more than the horizontal distance B from the lower edge of the club face to the position of a backmost end of the club head on the top-side,
• wherein
• the loft angle of the club face is 34 degrees or less, and
• wherein
• the top thickness which is the thickness of the top measured in a perpendicular direction to the club face is in a range from 3.0 to 10.0 mm.

• wherein
• the iron golf club head is composed of:
• a head main body having the club face, a weight member having a specific gravity larger than that of the club head main body, and
• a fixing member fixed to the head main body and covering the weight member.
