Ultrasonic treatment apparatus

An ultrasonic treatment apparatus comprising:

• a treatment-ultrasonic-wave irradiator that is disposed facing a surface of biological tissue and that is configured to irradiate the biological tissue with focused ultrasonic waves, thus heating a vicinity of a focal point of the focused ultrasonic waves positioned at a deep portion in the biological tissue to a temperature that is equal to or greater than a thermal-denaturation temperature of the biological tissue;
• and
• a pre-heating-energy irradiator that is configured to irradiate the biological tissue with energy waves, thus heating the vicinity of the focal point to a temperature that is less than the thermal-denaturation temperature,
• wherein the pre-heating-energy irradiator is configured to irradiate the biological tissue with the energy waves from a direction that is different from the direction in which the treatment-ultrasonic-wave irradiator irradiates with the focused ultrasonic waves.
