Abstract
A thermal sensor in which, when an object to be measured is a water-based liquid, attachment of air bubbles to the external surface of the sensor is reduced to improve measurement accuracy. The thermal sensor has a sensing element () including a heat producing body and a temperature sensing body, a resin mold () for sealing the sensing element (), and a heat transmission member () for transmitting heat between the sensing element () and a water-based object to be measured. A part of the heat transmission member () is exposed from the resin mold () to form an exposed surface section. A hydrophilic film () formed of a silicon oxide film is applied to the exposed surface section and to that part of the surface of the resin mold which is positioned around the exposed surface section.
