Abstract

PURPOSE:To improve thermal responsiveness and to fix a heat sensitive element to a substrate in a stable state by disposing the heat sensitive element onto a base consisting of a resin notched at the point corresponding to the temp. sensitive part thereof. CONSTITUTION:The sheet-like base 5 consisting of the synthetic resin for which a polyimide resin is used has the notch 8 sized 3X3mm, connecting electrodes 6, and lead parts 7 connecting the electrodes 6 and external drawing out wires. The heat sensitive part 2 is so positioned as to enter the inside of the notch 8 and is connected by soldering in a juncture 4. The direct reception and transfer of heat between the temp. sensitive body and the base and the outflow of the heat to the base are, therefore, decreased and the temp. sensor having the excellent thermal response is obtd. if the temp. sensor is formed by using such structure.

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.

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.
