TEMPERATURE DETECTOR

PROBLEM TO BE SOLVED: To provide a temperature detector which can detect the temperature of a coil more accurately and more responsively while promoting reduction of size.SOLUTION: A temperature detector 1 includes: a thermistor element 10 having a thermosensitive body 11 and an electric wire 12; and a holder 20 making the thermistor element 10 attach to a coil element 9, the thermosensitive body 11 sensing heat of the coil element 9 and the electric wire 12 being electrically connected to the thermosensitive body 11. The holder 20 includes: a thermosensitive body holder 21; and an electric wire holder 22, the holder 21 holding a reinforcing part 13 of the thermosensitive body 11 arranged laterally along a surface 9A of the coil element 9 and having a first resin storage 41 containing a thermosensitive body contacting part 11S of the thermosensitive body 11, and the electric wire holder 22 holding the electric wire 12. The thermosensitive body contacting part 11S is in contact with the coil element 9, being contained in the first resin storage 41.SELECTED DRAWING: Figure 2 【課題】小型化を促進しつつ、コイルの温度をより正確で応答性良く検出することが可能な温度検出装置を提供すること。【解決手段】温度検出装置１は、コイル要素９の熱を感知する感熱体１１、および感熱体１１に電気的に接続される電線１２を有するサーミスタ素子１０と、サーミスタ素子１０をコイル要素９に組み付けるホルダ２０とを備える。ホルダ２０は、コイル要素９の表面９Ａに沿って横向きに配置された感熱体１１の補強部１３を保持するとともに、感熱体１１の感熱体接触部１１Ｓを包み込む第１樹脂溜まり４１が設けられる感熱体ホルダ２１と、電線１２を保持する電線ホルダ２２とを備えている。感熱体接触部１１Ｓは、第１樹脂溜まり４１に包み込まれた状態でコイル要素９に接触している。【選択図】図２
