A bat structure includes a central portion, two symmetrical opposite side enclosure portions, and two symmetrical opposite outer enclosure portions. The central portion has a square cross-section, and the two side enclosure portions and the two outer enclosure portions are wound around the four sides of the central portion in a staggered manner. Thus, the bat structure can provide a shock-absorbing effect to prevent the bat structure from being broken due to a larger shock, thereby increasing the lifetime of the bat structure. In addition, the batter can feel more comfortable when the bat structure hits the ball.
