Abstract
A temperature measuring apparatus consisting of a sensing element, a retaining element which retains the sensing element and which is made of a thermally conductive and electrically insulative material, a holding element which holds the retaining element, and a contact mechanism which elastically contact the retaining element with the top of the surface of the measured body. The sensing element is composed of a thin film thermistor formed on the electrically insulating layer on a substrate. A film having the thermally conductive and electrically insulative material may be inserted between the measured body and the contact area of the retaining element. The retaining element is composed of the polyimide film and a flexible copper lead foil formed on the film and connected to the electrodes of the sensing element. The contact mechanism is composed of a pressing frame with at least one pressing arm which presses the contact part of the retaining element to the measured body and which is located adjacent to the contact zone.
