Claim 4:
5. A non-transitory computer readable storage medium storing a program executed by a computer of a temperature measuring device including an ultrasonic sensor attached to a rear surface side of a structural body having a multilayer structure, the program comprising the steps of:
acquiring, through the ultrasonic sensor, a signal of a reflected wave of an ultrasonic wave incident at an internal side of the structural body;
extracting, from the signal of the reflected wave, a domain including a reflected wave reflected on a surface on the internal side of the structural body;
identifying, based on a signal of the reflected wave in the extracted domain, a temperature of the surface on the internal side of the structural body; and
measuring a reference temperature of the structural body, wherein
in the step of identifying, the temperature of the surface on the internal side of the structural body is identified based on both of intensity of the signal of the reflected wave which indicates an amplitude of the reflected wave and the reference temperature by referring to an interface temperature table which defines a relationship between the amplitude of the reflected wave, the reference temperature, and the temperature of the surface on the internal side of the structural body.
