<p>The invention relates to improving the resistance to corrosion and reliability in a temperature sensor (15) with a lead wire (3, 22). The present invention relates to a temperature-sensing device including an element with a resistance value varying with a temperature change, a lead extending on the axis of the element, and a resin coat (5) surrounding the element, wherein a number of hydrophobic inorganic fillers with an average particle size of 5 µm or less exist on a surface of the resin coat (5). The present invention also relates to a temperature sensor (15) including an element with a resistance value varying with a temperature change, a sealing electrode (2) electrically connected to each of both ends of the element, a lead wire (3, 22) electrically connected to each of the sealing electrodes (2) and extending on the axis direction of a composite body formed of the element and the sealing electrode (2), an inorganic insulating member surrounding the element and covering at least part of the sealing electrodes (2) to fix the element and the sealing electrodes (2), and a resin coat (5) covering at least a connecting portion between the electrode and the lead wire (3, 22), wherein a number of hydrophobic inorganic fillers with an average particle size of 5 µm or less exist on a surface of the resin coat (5).</p> |
