Abstract
A planer heater includes a thin metal plate having a relatively high specific resistance such as stainless, nichrome, nickel-chrome iron alloy, etc. The thin metal plate is subjected to etching-working to form a mesh-like heat generating body, opposite ends of which are provided with terminal portions for connection into an electrical circuit.
