PROBLEM TO BE SOLVED: To provide a temperature sensor for liquid vessel for reducing errors produced at a temperature measurement result by a temperature measuring resistor, and for accurately measuring the actual liquid temperature. SOLUTION: The liquid vessel temperature sensor partially constitutes the bottom face or a side face of a vessel, measures the temperature of the liquid in the vessel, and is attached to an attachment hole provided on the bottom face or the side face of the vessel for accommodating the liquid. The liquid vessel temperature sensor comprises an attachment screw for attaching the sensor to the attachment hole, a lead wire inserted into an insertion hole, provided in the attachment screw and protruding from a tip of the attachment screw, the resistance thermometer provided at a tip of the protruding lead wire, a protective thermal insulation resin for coating the lead wire protruding from the tip of the attachment screw and a side face of the resistance thermometer, and a protective cylinder for surrounding at least a part of the lateral circumference of the protecting thermal insulation resin. The protective thermal insulation resin is formed so as to have substantially equal diameter as the diameter of an attachment section body or larger. COPYRIGHT: (C)2006,JPO&NCIPI
