PROBLEM TO BE SOLVED: To enhance the efficiency of coating work of a part having ruggedness such as an inner surface of a socket or an outer surface of an inserting opening of a tubular body. SOLUTION: In the method of coating the tubular body p having the socket 3 in one end and the inserting opening 2 in the other end, powder electrostatic coating is applied onto the inner surface 3a of the socket 3 by arranging a nozzle 10 for coating in the socket 3, moving the nozzle 10 back and forth from a tube end part 3b of the socket 3 side to the deep part 3c of the socket 3 while rotating the tubular body p around the tube axis and discharging electrified powder paint from the nozzle 10 during the back and forth movement from the tube end part 3b to the deep part 3c. In the powder coating, the so-called electrostatic powder coating is applied and a coating surface having a uniform film thick free from unevenness is formed by moving the nozzle 10 back and forth from the tube end part 3b of the socket 3 side to the deep part 3c of the socket 3.
