To provide a microwave baking furnace in which an inner wall which constitutes a heating element partitioning a baking chamber is prevented from being damaged due to a thermal shock, and the life time thereof can be extended. A microwave baking furnace 31 includes a partition wall 35 of a heating element 33 which partitions a baking chamber and which has an inner wall 35 b made of a material self-heating by microwave radiation and transmitting part of microwaves radiated thereto, and an outer wall 35 a made of an insulating material permitting the microwaves to be transmitted therethrough and covering an outer circumference of the inner wall 35 b. A clearance 39 , which serves as a convection path of heat inside the baking chamber 23 , is secured between the inner wall 35 a and the outer wall 35 a. The inner wall 35 b is attached to the outer wall 35 a such that it can move relative to the outer wall 35 a by a predetermined distance in all directions.
