PROBLEM TO BE SOLVED: To provide wooden combination board play equipment by which a wooden play unit is reinforced and resistance force against an instantaneous load is sufficiently showed compared with conventional equipment by the simple combination of wooden boards. SOLUTION: A board body consisting of a combination board member where thin wooden boards are stacked and arranged in a grid shape is provided with a requested curvature. Play equipment is constituted of a single board body or by combining a plurality of board bodies so that the resistance force is increased by using the grid shape stacked thin boards. Then, a problem in a conventional manner is solved.
