A loess blackboard and an eraser for the same are provided to be harmless for human bodies by preventing dust of chalk or volatile materials of an organic solvent and to let children use the loess blackboard for playing or study by making the size small. A loess blackboard(1) is produced in the shape of a plate by using yellow loess as main material. A case(2) exposes the front surface of the loess blackboard. A net core material is inserted into the loess blackboard to reinforce the strength of the loess blackboard. A heating body is installed inside to heat the loess blackboard. An eraser attached with a heat plate applies heat to the surface of the loess blackboard.
