Claims

[Scope of utility model registration request]

A heating element consisting of an alternating laminate of PTC heat generating material and electrodes, the electrodes being arranged so as to be drawn out to two mutually different end faces of the PTC heat generating material, and one electrode and an adjacent electrode. P between
A through hole is formed in the TC heat generating material in a direction parallel to the electrode and at a depth that does not reach the electrode, leading to two other end faces other than the end face of the PTC heat generating material, and is exposed to the end face. A heating element characterized in that the entire outer peripheral surface of the element other than the electrodes is covered with a PTC heating element or other ceramic layer.
