ていた。2. Description of the Related Art Conventionally, in a heating furnace using microwaves as a heat source, a door for shielding microwaves is provided at an entrance / exit to prevent leakage of the microwaves. When loading or unloading the object to be heated, the furnace detects the time when the object to be heated reaches the vicinity of the entrance / exit with a sensor etc. and stops the conveyor and also the door with microwave irradiation stopped. The object to be heated must be loaded and unloaded by driving the conveyor after that, and therefore the object to be heated cannot be continuously heated. It requires a long time, requires a large amount of heat energy, and is provided with a door, a sensor, and the like, which has a drawback that the structure becomes complicated.

Main furnace body in the shape of a tunnel in which a microwave transmitter 4 is provided in a transfer path of a transfer conveyor 3 that transfers the base material W containing
10 and the opening of the entrance and exit of the main furnace body 10
A tunnel-shaped auxiliary furnace body 12, 12a is connected to 11, 11a.
The auxiliary furnace bodies 12 and 12a are formed by continuous forming and the base material W
Set at least one or more to completely hide the heating furnace 5
The substrate W is continuously transported by the transport conveyor 3 ,
Since the base material W that is continuously conveyed is heated by irradiating the microwave from the microwave transmitter 4 into the furnace body 10, most of the microwaves are absorbed and heated by the base material W inside the main furnace body 10. However, it is reflected inside the main furnace body 10 ,
The microwave that cannot be completely absorbed by the base W is the auxiliary furnace body 12,
12a, the auxiliary furnace body 12, 12a
Since the base material W containing water is always located in the inside, microwaves which are about to leak to the outside from the auxiliary furnace bodies 12 and 12a are absorbed by the base material W to completely prevent the microwave from leaking to the outside. It can be prevented.
