To provide a baking method for a batch-type kiln for quickly heating treated objects to a high temperature of 1,000°C or higher and uniformly baking them.

The batch-type kiln is constituted by arranging, in a furnace, a plurality of stages of a shelf structure formed by juxtaposing bar-like or pipe-like heaters, and disposing auxiliary heaters on or near the inner wall surface of the furnace. In the method for placing a setter loaded with the treated objects on the shelf structure and heating and baking the treated objects, a heater used as the auxiliary heater is provided with a non-heating part at the center part with a 10-25% length of the heating part length, and the auxiliary heater and the setter are spaced by a distance of 3d-10d (d is a diameter of the auxiliary heater) to carry out heating and baking.
