PROBLEM TO BE SOLVED: To provide an ultrasonic sensor head of an ultrasonic nondestructive inspection device which has a simple configuration and high durability, and which enables maintenance of stable inspection precision. SOLUTION: In an ultrasonic sensor head 10 of an ultrasonic nondestructive inspection device, which nondestructively inspects an object to be inspected according to a received waveform of the ultrasonic waves by an ultrasonic oscillator, a cylindrical holder 12 is connected to the edge 11a of an ultrasonic oscillator 11 which receives and sends the ultrasonic waves, and a contact medium of soft gel materials 13 is located, while a base edge 13a faces to the edge 11a of an ultrasonic oscillator 11 in the holder 12 and in a state with the edge part 13b protruded from the edge opening part 12b of the holder 12. By pressing the edge part 13b of the contact medium 13 against an object to be inspected 50, the ultrasonic oscillator 11 and the contact medium 13, and the contact medium 13 and the object to be inspected 10 adhere to each other, and deformation of the edge part 13b is curbed by the edge opening part 12b of the holder 12.
