PURPOSE: To shorten the making time of breads and rapidly obtain the just baked breads by baking a bread dough with both an external heating means and an inner heating means using microwaves and immediately subjecting the baked bread to vacuum treatment.

CONSTITUTION: A bread dough prepared by a conventional method or a frozen stored bread dough is received in a baking chamber 11 having an airtight structure, and subsequently baked with both an external heating means comprising a heated air-generating device 2 and a heater 3 and an inner heating means using microwaves, such as magnetron 4. Just after the bread dough is baked, the baking chamber is subjected to vacuum with a vacuum device 8 and the baked bread is allowed to stand under the vacuum to reduce water content in the bread dough.
