向上し、小型に形成できる効果がある。The temperature detector of FIG. 1 detects the temperature by contacting a portion of the surrounding glass k on the front surface thereof with each device.
When the back side of the alumina substrate a is brought into contact with each device, the distance to the thermistor d is too vacant, so that accurate detection is not possible. In order to detect the temperature by contacting the surrounding glass k with each appliance, the area should be as large as possible.
This is a problem because the known half is a connection part between the left electrode e and the right electrode f and the lead wire g. However, according to the present invention, a thermistor 4 is provided while leaving a narrow peripheral portion 3 on the front side 2 of a square plate-shaped alumina substrate 1, and a left electrode 5 and a right electrode 6 are attached to the left and right sides of the thermistor 4, respectively.
The left electrode 5 and the right electrode 6 have a left connecting portion 8 reaching the back surface 7.
And a right connecting portion 9 on the back surface, a connecting back left electrode 10 and a connecting back right electrode 11 connected to the left and right connecting portions 8 and 9 respectively.
And connecting the core wires 14 and 15 of the lead wires 12 and 13 to the connection back left electrode 10 and the connection back right electrode 11 respectively.
Since the temperature detector was welded at 6 and 17 and the periphery of the thermistor 4 was surrounded by the surrounding glass 18, the heat receiving area of the thermistor 4 was increased, the accuracy was improved, and the size was reduced as compared with the known example of FIG. There is an effect that can be formed.
