PURPOSE: A microwave oven has many high voltage transformers, and simplifies a circuit structure. CONSTITUTION: A microwave oven includes a power unit(1), a party power line, many parallel lines in parallel connected to the party power line, and many high voltage transformers(10,20) mounted to the parallel line. A party safety fuse(11) and a party safety switch(12) are mounted in the party power line. The party safety fuse and the party safety switch are connected in series to each other. Thereby, a circuit structure is simplified, and the assembling work becomes easier.
