PROBLEM TO BE SOLVED: To provide an electric furnace with piping for accurate temperature control and management. SOLUTION: An electric furnace 1 is provided with piping H flexed in parallel for allowing fluid to be treated to flow, and a temperature controlling part 2 for adjusting the temperature of the liquid flowing through the piping H. The temperature controlling part 2 is formed along the arrangement direction of straight pipe parts H1-H9 of the piping H, and at the same time is arranged opposingly while sandwiching the piping H. Since the temperature controlling part 2 is arranged opposingly while sandwiching the piping H, each part of the piping H being flexed in parallel is allowed to uniformly face the temperature controlling part 2. As a result, temperature can be controlled uniformly, thus performing stable temperature control and management.
