Claims

[Scope of utility model registration request]

A heater coil with terminals 3 connected to both ends is inserted into a metal pipe 1, and an electrical insulating material 2 is filled between the metal pipe 1, the heater coil, and the terminal 3.At the end of the sheathed heater, the metal pipe 1 and terminal 3
An electrical insulator 4 is inserted between the terminals 3 to ensure the insulation distance, and a locking portion is deformed to a larger extent than the inner diameter of the electrical insulator 4 at a portion of the terminal 3 that protrudes from the electrical insulator 4. 3a, and the electrical insulator 4 is brought into pressure contact with the electrical insulator 2 by the locking portion 3a.
