PROBLEM TO BE SOLVED: To provide an ultrasonic inspection device, capable of measuring the distance and inclination with an inspection target surface of an ultrasonic transducer with high accuracy and is capable of acquiring inspection data and an inspection image of high quality, and to provide an ultrasonic inspection method. SOLUTION: The ultrasonic transducer 5 is provided with distance measuring ultrasonic sensors 7a and 7b for detecting the distance from the surface of an inspection target 1 and the inclination with respect to the surface of the inspection target 1 so that the distance and inclination to the inspection target 1 of the ultrasonic transducer 5 are controlled, on the basis of the data detected by the distance measuring ultrasonic sensors 7a and 7b. At least a part of the ultrasonic waves from the distance measuring ultrasonic sensors 7a and 7b is received, during the execution of aperture combining processing, wherein the transmission-reception of the ultrasonic transducer 5 is not performed.
