Abstract
A temperature sensor including a thermosensitive element and a ceramic body having a hollow section which surrounds the thermosensitive element airtightly. The thermosensitive element is formed on a heat-sensing surface side of the ceramic body having the hollow section. The hollow section is formed at a position which is shifted to the heat-sensing surface side with respect to the center of the temperature sensor. The ceramic body includes a heat-sensing surface side ceramic layer (1) having the thermosensitive element (4) disposed thereon, a spacer ceramic layer (3) having an aperture, and a substrate ceramic layer (2) serving as a substrate.
