産業上の利用分野
本発明は、自動車用、家庭電化製品用、工業計器などに

精度が悪いものとに大別でき、用途に応じて使い分けら
れている。Conventional technology Conventional temperature sensors are highly accurate but are expensive and difficult to handle, while others are simple and can be used in large quantities.
They can be broadly classified into those with low accuracy and those with low accuracy, and are used depending on the purpose.

のが要求されている。However, with recent rapid advances in electronics, there has been a demand for temperature sensors that are robust, can be used in large quantities, and have high accuracy, especially precision temperature sensors for automobiles. In particular, for automobiles, there is a need for a device that is inexpensive, compact, highly accurate, has a wide temperature range, exhibits a linear resistance change, is resistant to vibration, and has good thermal responsiveness.

金線を1本ずつセラミックボビン等にまきつけて作製し
ていくため大量生産は不可能であって相当高価なものと
なっていた。Conventionally, platinum resistance thermometers have been used as temperature sensors, but since platinum wire is used, the resistance value is 6oΩ,
The resistance is as low as 100Ω, which makes the peripheral circuitry complicated and susceptible to noise from the peripheral circuitry.In addition, the shape is large, and it is susceptible to vibrations and shocks. Furthermore, there is a limit to how thin platinum wire can be made, so a considerable amount of expensive platinum wire is used, and mass production is not possible because each platinum wire is wound around a ceramic bobbin, etc. Although possible, it was quite expensive.
このような問題点を解決するために、白金線の代わりに
白金の厚膜や薄膜を用いたいくつかの方法が試みられて
いる。In order to solve these problems, several methods have been attempted using thick or thin platinum films instead of platinum wires.
第3図はその一例であって、絶縁基板11上に白金膜1
2を形成し、フォトエツチングあるいはレーザトリミン
グにより抵抗値を調整している。FIG. 3 shows an example of this, in which a platinum film 1 is placed on an insulating substrate 11.
2 is formed, and the resistance value is adjusted by photoetching or laser trimming.
13は電極、14はリード線である。13 is an electrode, and 14 is a lead wire.

通じての熱の授受が少なく、安定して固定できることが
必要であった。On the other hand, the substrate type can be manufactured inexpensively using a manufacturing method suitable for mass production, and its performance is stable and precise. However, in order to use it as a flow sensor with excellent thermal response, it is necessary to It was necessary to have a stable fixation with little friction.
