The gas sensor is equipped with a sensor device, a plurality of electrode springs contacting with electrodes and of the sensor device, an insulator retaining the electrode springs, and a plurality of leads connected to the respective electrode springs. Each of the electrode springs includes a retained portion retained by the insulator and a contact portion which is bent and inclined from the retained portion toward a front end side of the sensor device in the lengthwise direction. The contact portion is elastically deformed in contact with the electrode. Each of the electrode springs also includes a bent portion between the contact portion and the retained portion. The bent portion constitutes a base end of the contact portion and is oriented toward the base end side of the gas sensor in the lengthwise direction, thereby enabling the length of the sensor device to be decreased and improving the heat resistance of the electrode springs.
A gas sensor which includes a sensor device, a plurality of electrodes disposed on a base end side of the sensor device in a lengthwise direction of the sensor device, a plurality of electrode springs placed in contact with the electrodes, respectively, an insulator which retains the electrode springs, and a plurality of leads which are connected to the respective electrode springs and extend outwardly from base ends of the electrode springs in the lengthwise direction, wherein each of the electrode springs includes a retained portion which is retained by said insulator, a contact portion which is inclined relative to the retained portion, bent in a turned form from the retained portion so as to face the retained portion, and placed in contact with said electrodes, and a bent portion which is formed between said contact portion and said retained portion, and in that said bent portion is located on a base end of the contact portion, and the contact portion is in contact with the electrode using spring property of the bent portion.
