摘要： A lead wire for a sensor has a conductor unit including at least stainless steel wires and copper wires. By setting the cross-sectional percentage of the stainless steel wires in the conductor unit within the range of 30 to 70%, it is possible to obtain a lead wire having low electrical resistance, and high flexibility, tensile strength and elasticity. There are preferred values in hardness and heat treatment of the stainless steel wires. The copper wires are preferably coated with an antioxidant film. The lead wire may include hybrid wires stranded together and obtained by integrally molding or forming stainless steel and copper. It is preferable that the lead wire is coated with an insulating coating material such as a Teflon type resin.

摘要： A ceramic heater is provided which may be built in a gas sensor to heat a sensor element up to a desired activation temperature. The ceramic heater includes a pair of electrical conductors formed on a ceramic body. Each of the conductors is equipped with a terminal. Leads are joined to the terminals for supplying electrical power to the conductors. Joints between the leads and the terminals are covered hermetically by a seal, thereby minimizing corrosion thereof to avoid disconnections of the terminals from the leads. This improves the durability of the ceramic heater.
