Claim Text:
1. An ultrasonic flaw detector comprising: an ultrasonic probe that emits an ultrasonic wave on an object to be inspected and receives a reflected ultrasonic wave from the object; circuitry configured to control a plurality of ultrasonic elements to emit an ultrasonic wave from the ultrasonic probe and to control a reflected ultrasonic wave from the object; and a design database that stores in advance data on a surface shape of a surface of the object; wherein the circuitry is configured to adjust a number of the plurality of ultrasonic elements to be driven based on the surface shape stored in the design database and to calculate a plurality of incident positions on the surface of the object where the ultrasonic wave enters based on a refraction angle of the ultrasonic wave in the object and the surface shape.
