Abstract
A high frequency heating device having a switching member screwed into a screw hole formed in a flange and fixed to the exterior. When the exterior is fixed to the body, a through-hole formed at that portion in the rear plate of the body through which the switching member passes is too large for the switching member. Thus, while the switching member is fixable to the exterior, the switching member cannot be fixed to the body onto which the exterior is not mounted. Therefore, a high frequency heating device can be provided, wherein an exterior switch more surely keeps the power supply circuit open when the exterior is removed.
