<P>PROBLEM TO BE SOLVED: To heat an object to be heated efficiently and uniformly with a simple and compact structure, without using a table, an antenna, a rotation mechanism of a phase shifter, or the like. <P>SOLUTION: A waveguide 100 transmitting microwaves generated by microwave generation means 50 to a heating chamber 200 can distribute a plurality of openings for radiating microwaves widely to the heating chamber 200, by widening the second width in a microwave radiation section. When the first width 101 at an inlet 110 for connection with the microwave generation means 50 is made narrower than a second width 102, a microwave heating device capable of heating an object to be heated uniformly with a compact and simple microwave power supply configuration, without using a rotation mechanism, can be provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
