Abstract: A microwave heating device which enables use of a conveyor with a metallic belt is provided, as is a baking facility having the device. The device includes a conveying means for conveying objects to be heated; a microwave generating means for emitting microwaves to the objects to be heated conveyed by the conveying means; a rotating member that is provided between the objects to be heated and the microwave generating means, and that has a rotary vane configured to reflect the microwaves emitted from the microwave generating means; and a shielding member configured to reflect the microwaves, provided between the rotating member and the objects to be heated. The conveying means has a metallic holding member for holding the objects to be heated, and the shielding member has a microwave transmitting unit for transmitting the microwaves. The microwave transmitting unit extends in a direction orthogonal to the conveyance direction of the objects to be heated conveyed by the conveying means.
