ある。2. Description of the Related Art Conventionally, as shown in FIG. 2 (a), a pair of electrodes 2 are formed by screen-printing a conductive paste on an insulating substrate 1 such as a glass ceramic substrate, and then a resistor is formed. There is a planar heating element formed by screen-printing a paste in a linear pattern to form the resistance heating element 3, and drying and firing at a predetermined temperature.

Will make a difference. For this reason, uniform heating may not be possible from the entire surface of the sheet heating element, or the portion with high resistance may be disconnected due to local heating.

However, in the above-mentioned conventional sheet heating element, it is difficult to find an appropriate trimming position, or the resistance is adjusted. There was a problem that the value did not change significantly.

A conductor that extends transversely and short-circuits the resistance heating element is formed in a planar heating element formed at equal intervals between the electrodes, and the sum of the resistance values of the plurality of resistance heating elements is the resistance value between the conductors. Therefore, if you measure the resistance between each conductor,
It has an effect that the unevenness of the resistance value can be detected, and a plurality of resistance heating elements between the conductors can be cut one by one to perform trimming so that the resistance values of the conductors are equalized.
