PROBLEM TO BE SOLVED: To provide a gas sensor having little possibility of breaking a lead wire, allowing the use of a lead wire having small line diameter and low rigidity, and capable of reducing the power consumption. SOLUTION: The lead wire 6 is joined to a heater electrode 3 and a sensitive body electrode 8 by an ultrasonic thermo compression bonding, whereby as compared with the case of joining the lead wire to the electrode by another general welding method, the wire 6 is hard to break, so that the lead wire 6 having a small wire diameter and low rigidity can be used. The use of the lead wire 6 having a small wire diameter can reduce radiation due to heat transmitted to the lead wire 6, so that the power consumption of a heater for heating the sensitive body membrane 9 to a designated temperature can be reduced. |
