Abstract
A planar heater for a liquid crystal element comprises a thin metal plate having a relatively high specific resistance such as stainless, nichrome, nickelchrome 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 elecrtrical circuit.
