An electrical wire coating apparatus forms a coating layer on an outer surface of an electrical wire. The electrical wire coating apparatus has a coating material for forming the coating layer, a pair of sponges that is elastic and configured to be impregnated with a coating liquid made of a coating material and a solvent in which the coating material is dissolved, an accommodating tub that accommodates the pair of the sponges, a moving unit that holds the electrical wire and moves the electrical wire and the accommodating tub relative to each other in a direction orthogonal to a longitudinaldirection of the electrical wire, and a pair of indentations that allows the electrical wire moving relative to the accommodating tub to be accommodated into the accommodating tub.
