PROBLEM TO BE SOLVED: To provide a molten salt electrodepositing device and a molten salt electrodepositing method by which a coating layer can easily be formed by using a molten salt electrolytic bath shallower than the length of the bar-shaped or tubular member to be treated. SOLUTION: This device contains a cylindrical body 3 to be stored with a salt, a molten salt melting means 5 for heating and melting the salt excepting the vicinity of the bottom part of the cylindrical body 3, an electrode 7 arranged on the inside of the cylindrical body 3 and a power source part 15 electrically connected to the electrode 7 and the bar-shaped or tubular member 23 to be treated, the cylindrical body 3 has a bottom board 17 clogging the bottom part, and the bottom board 17 is formed with a through-hole 19 through which the member 23 to be treated can be inserted and passed. In this way, the cylindrical body 3, i.e., the molten salt electrolytic bath 25 is relatively moved to the member 23 to be treated, by which the surface of the member 23 to be treated can be successively be formed with a coating layer, so that the coating layer can easily be formed by using the molten salt electrolytic bath 25 shallower than the length of the bar-shaped or tubular member to be treated.
