PROBLEM TO BE SOLVED: To improve a multipurpose use by forming antiskid recessed grooves on a top surface of a sectionally triangular body made of synthetic resin foaming material whose base side has one substantially orthogonal angle part and the other acute angle part. SOLUTION: A multipurpose inclination board 1 made of synthtic resin foaming body having a sectionally triangular shape has one angle 4 substantially orthogonal in its bottom side and the other angle 5 acute for providing a slant surface 6 easy to climb. The surface 6 has recessed grooves 2 or a protrusions serving as antiskid members thereon. A foaming material formed basically of polyethylene resin copolymerized with methacelon catalyst is adhered to a top/bottom surface of the board 1 so that it serves as antiskid material by which antiskid an stable use of the board 1 is assured when it is layed on the ground or the like. A rubber sheet is layed on the surface 6 so as to prevent the synthetic resin foaming material from being damaged and improve an antiskid condition. Accordingly, a stepped difference is eliminated, an easy movement is ensured with its lightness, aged persons can use it with the antiskid conditions, and users can use it as a physical exercise tool while a balance feeling thereof on the inclined slope is improved.
