PROBLEM TO BE SOLVED: To provide an ultrasonic treatment apparatus which can surely carry out an ultrasonic treatment of a material to be treated by uniforming sound pressure distribution in a treatment liquid using a simple constitution. SOLUTION: The ultrasonic treatment apparatus has a treatment tank for storing the treatment liquid and also immersing the material to be treated into the treatment liquid, a vibration generating member which is installed on the bottom side of the treatment tank and generates an ultrasonic vibration, and a vibration transmitting member which contacts with the vibration generating member and affects the ultrasonic vibration from the vibration generating member to the treatment liquid, wherein a plurality of convex spherical surfaces are arranged on the surface of the vibration transmitting member.
