PROBLEM TO BE SOLVED: To provide a multi-channel temperature measuring circuit improved such that the multi-channel temperature measuring circuit provided with a plurality of thermometric resistors are materialized to continuously, and simultaneously supply the current, moreover even at the time any of thermometric resistors among the plurality of thermometric resistors are disconnected, the current is supplied continuously to the remaining resistors. SOLUTION: A multi-channel temperature measurement circuit A includes a plurality of thermometric resistors R1 to R10 which are connected serially so as to be supplied with current from a constant current source I. Each of thermometric resistors R1 to R10 is parallelly connected with current detour circuit Ry1 to Ry10 for making the current detour when any one among the thermometric resistors R1 to R10 is disconnected.
