Claim:
1. A method for providing an electrostatic coating on a coating target having, on a coating surface, a stepped portion extending in a predetermined direction where the stepped portion is defined as a portion having a relatively projected side and a relatively recessed side, the method comprising: a first step of providing an entire surface coating on the entire coating surface of the coating target; and a second step of providing, after the entire surface coating, a follow-up coating along the stepped portion extending in the predetermined direction so that paint mist adheres more to the relatively-recessed side of the stepped portion, wherein a rotating bell-type coating gun by which the paint mist is supplied while swirling about a center of a bell is used in the follow-up coating, and when the coating gun is moved in one direction along the stepped portion extending in the predetermined direction, swirling of the paint mist is reduced on one side of a movement line of a bell center of the coating gun due to air resistance caused by the movement of the coating gun, and the coating gun is moved only in the one direction along the stepped portion, with the one side facing the relatively-recessed side of the stepped portion.
