The present invention is capable of warming to the living body deep, to provide a heating device for fat diagnostic also difficult to create a safety hazard to use in the vicinity of the bone tissue. A first electrode 11 A single side is brought into contact with transmission and reception surfaces other surface while being abutted to the subject S is transmitted and received ultrasonic waves of the ultrasonic diagnostic probe 20, the first electrode to be disposed in a position facing each other across the measurement area of the subject, a second electrode 12 on one side is brought into contact with the subject, the high frequency power for heating between the first electrode and the second electrode consists applied high frequency power source 13. the first electrode 11 is made of a material which transmits ultrasound and having a conductivity, as the second electrode 12 is made of a material having conductivity, ultrasonic diagnostic using a probe to measure the ultrasonic echo signals before and after heating of the measurement region and performs the fat diagnosis based on ultrasound velocity variation calculated from the heating before and after the ultrasonic echo signal.FIELD 1【課題】生体深部への加温が可能であり、骨組織の近傍で使用しても安全上の問題が生じにくい脂肪診断用の加温装置を提供する。【解決手段】片面が被検体Sに当接されるとともに他方面が超音波診断用プローブ20の超音波を送受する送受面に当接される第一電極11と、第一電極に対し被検体の測定領域を挟んで対向する位置に配置され、片面が被検体に当接される第二電極12と、第一電極と第二電極との間に加温用の高周波電力を印加する高周波電源13とからなり、第一電極11は導電性を有するとともに超音波を透過する素材からなり、第二電極12は導電性を有する素材から構成されるようにして、超音波診断用プローブを用いて測定領域の加温前後の超音波エコー信号を計測し、加温前後の超音波エコー信号から算出した超音波速度変化に基づいて脂肪診断を行う。【選択図】図1
