摘要： An eraser capable of erasing characters and the like written on paper with a ball-point pen, fountain pen, typewriter, word processor, color pencil or the like. The eraser has an integral structure composed of plural types of eraser pieces (20, 22, 24) having different hardnesses and an abrasive material (26), the eraser pieces and the abrasive material existing respectively in a particulately dispersed state. A method for manufacturing such eraser comprises steps of kneading plural types of major eraser materials which have been previously vulcanized and shaped at need with an abrasive material and vulcanizing and shaping the resulting mixture. These plural types of major eraser materials are such that erasers having different hardnesses can be produced if each of the major eraser materials is either vulcanized or heated and shaped alone and that particles of the major eraser materials exist independently from one another even if these materials are kneaded.
