ABSTRACT:
A resistor element for determining a parameter, including a ceramic support having a bearing surface, an electrically resistive body formed on the bearing surface of the ceramic support, a conductor or conductors electrically connected to the electrically resistive body, the conductor(s) having a lower thermal conductivity than a conductor made of platinum, and an adhesive for securing the conductor(s) to the ceramic support. The conductor is defined by a lead wire made of an alloy and a covering layer made of a metal which covers the lead wire. The adhesive contains at least one metal of which at least an outer surface of each conductor is formed, so as to increase bonding strength between the conductor(s) and the adhesive.
