ABSTRACT:
To realize an air guide of a radio-frequency heating apparatus that enables fixing of a lamp without use of a vis though it is made of a metal plate material. An air guide9made of a metal plate material is formed with two inverted-L-shaped nails15. A holding portion13of a lamp12is hooked on the nails15and a waveguide holding plate19is brought into contact with an opposed surface of the holding portion13of the lamp12. As a result, the lamp12can be fixed without using a vis and hence a step of fixing the lamp12with a vis can be eliminated. An inexpensive configuration can be realized that is free of fear that a disconnection may occur in a filament due to vibration.
