PROBLEM TO BE SOLVED: To provide a shelf board possible to solve the problem that it often causes a slight injury of a user without impairing rigidity of the shelf. SOLUTION: Multiple latitudinal wires and multiple longitudinal wires with a plane view join at each cross point to form a grid-like surface body. Each edge of this surface body is provided with a pair of reinforcing beams in upper and lower thereof. A zigzag reinforcing wire is stretched between the upper and the lower reinforcing beams to form a shelf board. An edge of the reinforcing wire is arranged with a space from both of the upper and the lower reinforcing beams and a tip corner is eliminated to prevent a slight injury of a user at a finger due to the tip of the reinforcing wire.
