It is aimed to provide an electric stove which is further improved to be able to further reduce a loss in terms of thermal efficiency by further increasing the reflection efficiency of heat rays on a mirror surface portion. An electric stove 10 includes electric heating elements 36 arranged at a distance from a position right below targets to be heated W, a first mirror surface portion 12 arranged to surround the electric heating elements 36 and configured to reflect heat rays radiated from the electric heating elements 36, and a second mirror surface portion 14 arranged below the electric heating elements 36 and configured to collect the heat rays reflected by the first minor surface portion 12 to a side below the targets to be heated W by reflecting the heat rays substantially immediately upwardly. The first minor surface portion 12 includes a plurality of partial elliptical mirror surface portions a to e having one focus near the electric heating elements 36 and the other focus below the electric heating elements 36, and the second minor surface portion 14 includes a partial elliptical minor surface portion s having one focus near the electric heating elements 36 and the other focus below the electric heating elements 36.
