摘要：
A pressing device for smoothly performing pressing operation, an ultrasonic probe, and an ultrasonic diagnostic apparatus are provided.
The pressing device has a balloon installed on an ultrasonic transmission/reception surface of an ultrasonic probe and presses an object to be examined by the balloon.
The balloon has a hollow pressing unit made of an elastic material, a tube for charging/discharging liquid to/from the pressing unit, and an attachment part contiguous to the peripheral edge of the pressing unit and attaching the pressing unit to the ultrasonic transmission/reception unit of the ultrasonic probe.
The inner diameter of the attachment part or the pressing unit is set smaller than the outer diameter of the part of the ultrasonic probe on which the attachment part is attached.
Because tension is applied to the pressing unit, pressing operation can be started with a less amount of initial injection, and this makes the pressing operation smooth.
