Abstract: In a width dimension decrease portion forming a distal end of an ultrasonic probe, a width dimension decreases from a proximal direction toward a distal direction, so that a sectional area perpendicular to a longitudinal axis decreases from the proximal direction toward the distal direction. An intermediary portion continuous between a probe body portion and the width dimension decrease portion includes a width dimension increase portion in which the width dimension increases and a thickness dimension decreases from the proximal direction toward the distal direction at the same time. In the intermediary portion, the sectional area perpendicular to the longitudinal axis does not increase and does not decrease at a higher decrease rate than in the width dimension decrease portion toward the distal direction.

Abstract: A vibration generating unit includes a proximal side vibration transmitting section extended from a proximal end of the ultrasonic transducer toward a proximal direction. A proximal end of the proximal side vibration transmitting section is placed at a position apart from a reference antinode position toward the proximal direction by an extending dimension equal to an integral multiple of a half wavelength, when the reference antinode position is the closest to the ultrasonic transducer among antinode positions placed on the proximal direction side with respect to the ultrasonic transducer. The vibration generating unit includes an amplitude increasing section increasing an amplitude of the ultrasonic vibration transmitted toward the proximal direction in the proximal side vibration transmitting section.

Abstract: An inspection probe includes a vibration transmission portion transmitting an ultrasonic vibration along a longitudinal axis, and a vibration damping portion continuous with a distal direction side of the vibration transmission portion. the vibration damping portion damps the ultrasonic vibration by causing vibration energy of the ultrasonic vibration to be lost and converting the lost vibration energy to heat energy in a state that the vibration damping portion vibrates in a manner to follow the vibration transmission portion. An index section of the inspection probe serves as an index indicating a conversion amount to the heat energy in the vibration damping portion.
