PROBLEM TO BE SOLVED: To provide a method for manufacturing a thin and flexible ultrasonic thickness measurement sensor which can follow up even a curved surface to be measured, can eliminate various works before and after thickness measurement, while reducing the effort and time required for the thickness measurement, by always pasting a sheet to a part to be measured, can measure the thickness of a large number of parts simultaneously or measure the thickness continuously, and can be used even at a relatively high temperature of 300°C or higher.SOLUTION: The method for manufacturing an ultrasonic thickness sensor comprises: a process including the steps of mixing bismuth titanate powder with low-melting point glass powder of bismuth-based glass or the like, applying paste of the mixture to a surface of a thin-plate-like support member to make one of electrodes with at least its surface having conductivity, and heating and sintering the support member, thereby forming a relatively-porous and flexible thin bismuth titanate sintered compact layer over the surface of the thin-plate-like support member; and a subsequent process including the steps of attaching the other electrode, and performing a polarization process, thereby arranging the sensor to have flexibility generally. |
