TEMPERATURE SENSOR

To provide a temperature sensor with which it is possible to reduce a change to an inclination of temperature measuring performance even when installed aslant in a part whose temperature is to be measured.SOLUTION: A temperature sensor 1 comprises a thermistor 5, a pair of electric wires 6 electrically connected to a pair of leads of the thermistor 5, a heat collecting member 8 made of metal that is in contact with the top face of a battery cell that is the part whose temperature is to be measured, and a resin part 7 integrated with the foregoing. The heat collecting member 8 includes a pair of flat plates arranged facing each other and spaced apart from each other, with an element part of the thermistor 5 located therebetween, and a contact surface 81 of curved shape linking the pair of these flat plates together. The resin part 7 is composed of an insulating synthetic resin and includes, as an integral whole, a holding part 70 that holds the thermistor 5 and the heat collecting member 8, a pair of locking arms 71, and a pair of grip parts 72.SELECTED DRAWING: Figure 1 【課題】被測温部に傾いて設置されても、傾きに対しての測温性能の変動を小さくすることができる温度センサを提供する。【解決手段】温度センサ１は、サーミスタ５と、サーミスタ５の一対のリード部に電気接続された一対の電線６と、被測温部であるバッテリセル上面に接触する金属製の集熱部材８と、これらと一体化された樹脂部７と、を備えている。集熱部材８は、互いに間隔をあけて対向配置され、互いの間にサーミスタ５の素子部を位置付ける一対の平板部と、これら一対の平板部同士を繋いだ曲面形状の接触面８１と、を有している。樹脂部７は、絶縁性の合成樹脂で構成されており、サーミスタ５及び集熱部材８を保持した保持部７０と、一対の係止アーム７１と、一対の把持部７２と、を一体に有している。【選択図】図１
