The contact section includes a deformable resin material, is positioned outside the ultrasonic transducer, and forms a portion of the liquid filled section. The flexible section includes the deformable resin material and forms a portion of the liquid filled section. The ultrasonic transducer is configured to transmit ultrasonic waves through the contact section.
