Sensor stem, sensor device having the same, and method of manufacturing sensor device |
摘要 |
A sensor stem supporting a sensor element comprising a metal plate having a shape defined by press, the metal plate include a dent portion formed on a first surface of the metal plate, a step portion formed on a second surface of the metal plate facing the first surface, and a projection formed on the step portion for resistance welding. It is thus possible to obtain an excellent hermetic sealing of the sensor stem and a cap, which protects an oscillator, a circuit board and the like. The sensor stem can prevent a short circuit and can be lowered in height thereof.
