る。Effects of the Invention As is clear from the second embodiment, according to the surface heater of the present invention, a slurry consisting of mica powder, a plaster, and an inorganic binder is applied to a carrier tape and dried. With the surface sides of a pair of heat-resistant electrical insulating materials facing each other,
Since a heater element is inserted between them to form an integrated surface heater, it is possible to obtain a surface heater that has particularly high heat-resistant insulation and is resistant to heat shock.

面ヒータが得られる。Further, according to the manufacturing method of the present invention, a coating film mainly composed of glass or inorganic polymer is formed on the outer surface of the heater element and dried, and the surface side of the paired heat-resistant 1JlE electrical insulating material is coated on the outer surface of the heater element. The row culm is placed facing each other, and the heater ■ [noment is inserted between the row culm and the culm which is integrated by hot pressing.
After heat-treated culms, it becomes moisture resistant to heaters and T elements! Manufacture of a surface heater formed by forming an edge coating layer'/i= A surface heater with excellent moisture resistance, heat resistance, voltage resistance, and thermal shock resistance can be obtained even after aging.
