つていた。BACKGROUND OF THE INVENTION Conventional heater elements have a meandering pattern formed by photoetching. Since this method forms a pattern chemically, the resistance value varies widely. Therefore, the resistance value has been adjusted by constructing a removable short bridge as shown in, for example, Japanese Utility Model Publication No. 17356/1983.

The figure shows a cross-sectional view of the main part of the heater element of the present invention, and the processing method for the lath 1 is as shown in the figure, while making cuts A in the metal foil body 2 alternately and sequentially processing it in the B direction. I'll go. In this case, since a tensile force is applied in the direction B, the portion C is deformed and loses its flatness. Since flatness cannot be ensured as it is, roll processing is applied to create a smooth surface. Note that when machining the lath 1, the characteristics as a heater, especially in order to reduce the variation in resistance value, the cut width A, feed pitch D,
The stretching distance E needs to be precisely controlled. The plate thickness, material, cut width A, feed pitch D, stretching allowance E, number of laths 1, etc. of the metal foil body 2 are determined based on the design, and can be set arbitrarily. can.

行なう。 The heater element original plate thus formed is cut into a desired pattern. Since this cutting is done by press working, burrs naturally occur on the cut surface. If there are burrs on the cut surface, it may not be possible to secure insulation distance when laminating with plastic or the like. In addition, since the center value of the resistance value may deviate, rerolling is further performed for the purpose of crushing burrs and matching the center value of the resistance value.
