THERMISTOR ELEMENT AND TEMPERATURE SENSOR COMPRISING THE THERMISTOR ELEMENT

A thermistor element (1) comprising a thermistor main body (10) made of an electrically conductive sintered oxide and having a rectangular parallelepiped shape and a first covering layer which has reduction resistance is disclosed, said first covering layer (20) covering an entire periphery of the thermistor main body (10) and having an outer surface, at least a portion of which is an exposed outer surface exposed to the outside, wherein when a shortest distance in a straight line in the first covering layer (20) extending from a starting point on the thermistor main body (10) to the exposed outer surface is defined as an exposed layer thickness at the starting point, the first covering layer (20) is formed such that the exposed layer thickness measured by using any vertex of the rectangular parallelepiped thermistor main body (10) as a starting point is equal to or greater than the smallest one of exposed layer thicknesses measured by using, as starting points, points which are other than the vertex and are located on three sides and three flat surfaces which form the vertex.
