Claim:
1. A thickness measuring device, comprising: a plurality of elements arranged in line, each of the elements being configured to transmit an ultrasonic wave to a target object and acquirable of an echo signal with respect to the ultrasonic wave; a reception waveform storage configured to acquire and store reception waveforms of the elements at the time the respective elements transmit the ultrasonic waves; an echo waveform synthesizing module configured to obtain echo waveforms corresponding to the ultrasonic wave while scanning a focusing position of the ultrasonic beams, each of the echo waveforms being obtained by synthesizing the reception waveforms of the respective element stored in the reception waveform storage; an inner-surface focusing waveform acquiring module configured to acquire the echo waveform in which the beams are suitably focused on an inner surface of the target object, by evaluating each of the echo waveforms obtained by the echo waveform synthesizing module; and a thickness calculating module configured to calculate a thickness of the target object based on the echo waveform acquired by the inner-surface focusing waveform acquiring module.
