An electric oven includes a body, a food container and a lid covered on the food container. The body includes an outer body and an inner body combined together, with a heat-insulating layer formed between the outer and the inner body.
A heating tube and a heat preserving material are deposited in the heat-insulating layer, and the heating tube is laid around on an outer wall of the inner body. A bottom plate is fixed with the bottom of the body; a turning switch for setting heating temperature and time is fixed on an outer surface of the outer body, electrically connected with the heating tube and a power source.
The food container has an upper flange to be supported on an upper circumferential edge of the inner body for food to be placed therein for roasting and two grip members for taking the food container off the body.
