ABSTRACT:
A contact-type thermometer which is supported by fixing a contact plate having a supporting bar on both sides of an annular elastic member that is formed by connecting both sides of an elastic sheet. A temperature sensitive portion is arranged between the annular elastic member and the contact plate to hold a portion attached to the contact plate of the annular elastic member and the opposite side using the support. In addition, clearance fixing the supporting bar into a guide hole that is long from side to side in a holder such that the contact plate contacts an object to be temperature measured in parallel. The elastic force acting on the back of the contact plate under the condition of the elastically deforming annular elastic member becomes slightly flat, wherein the contact plate does not float more than a distance to the surface of the object to be temperature measured, so the temperature can be accurately measured.
