PROBLEM TO BE SOLVED: To provide an eraser containing an adipic acid-based polyester that is superior in easiness of collecting the erasing dregs, without impairing migration resistance and erasing ability.SOLUTION: A plastic eraser contains a substrate resin, a plasticizer and a filler. As the plasticizer, an adipic acid-based polyester (A) is used together with a liquid acrylic polymer (B) having a glass transition point (Tg) of 0°C or less, the adipic acid-based polyester is obtained by condensing an adipic acid, at least one kind of a polyhydric alcohol, and at least one kind selected from a monohydric alcohol or monocarboxylic acid. |
