To improve repulsion, control, and spin performance by improving the section shape of the head portion frame of a tennis racket.

When the section shape of a frame comprising a head portion and/or a throat portion is that width in an in-plane direction is H and the greatest thickness in an out-of-plane direction is T, the greatest thickness position of the greatest thickness T is in the range of 0.1 to 0.3 H from the outer face opposite to a struck ball face side, from the greatest thickness position toward the inside of the struck ball face side, a both side width direction frame portion is decreased in thickness while curving outward with great curvature, further, a gut groove is placed in the outer face center of the frame in the head portion, a gut hole passing from the center of the gut groove through the in-plane center is placed, and the gut groove is situated on the same face as a struck ball face.
