PURPOSE:To prevent the electrolytic corrosion of a conductor due to the water produced by a dew condensation during it is used by providing an auxiliary member of conductive material which is more corrosive than the conductor on an outside furface of a protection coating in a position near a resistance body and earthing the auxiliary member. CONSTITUTION:Two wire shaped auxiliary members are disposed parallel each other at a position near the both sides of the pattern 2a of a resistance body 2 on the outside surface of a protection coating 4, and is fixed with a bonding agent at several points. These auxiliary members are made of the conductive materials which are more corrosive than the conductor 3, for instance, Al, Zn, Mg, or the like in the case of the conductor 3 is made of NiCr/Au/Cr, and Zn, Mg or the like in the case of the conductor 3 is made of Al, and each of them is earthed and its potential is maintained at zero. |
