PROBLEM TO BE SOLVED: To provide a solid crayon erasable on a non-absorbing surface, capable of writing on the non-absorbing surface such as a white board, giving writings erasable by brushing with an eraser such as nonwoven fabric, which crayon realizes erasability like a white board ink by forming a uniform coating film to improve leveling property of the coating film, moreover, causes no cling on the white board, or the like, and is erasable by light touch. SOLUTION: This crayon erasable on the non-absorbing surface comprises at least an organic solvent, a resin soluble in the organic solvent, dibenzylidenesorbitol, tribenzylidenesorbitol or their derivatives, oil and a colorant, wherein the ratio of the colorant to the resin soluble in the organic solvent is 1/0.5 to 1/2.
