A sintered body for thermistor element of the invention is a sintered body for thermistor element containing Sr, Y, Mn, Al, Fe, and O, wherein not only respective liquid crystal phases of a perovskite type oxide and a garnet type oxide are contained, but also a liquid crystal phase of at least one of an Sr--Al based oxide and an Sr--Fe based oxide. FeYO.sub.3 and/or AlYO.sub.3 is selected as the foregoing perovskite type oxide, and at least one member selected from Y.sub.3Al.sub.5O.sub.12, Al.sub.2Fe.sub.3Y.sub.3O.sub.12, and Al.sub.3Fe.sub.2Y.sub.3O.sub.12 is selected as the foregoing garnet type oxide, respectively by the powder X-ray diffraction analysis.
