<p><P>PROBLEM TO BE SOLVED: To sequentially measure precise photoacoustic signals by solving problems such as the installation position relation between a photoacoustic generation source and acoustic detector due to body movement, deviation of a pushing pressure, acoustic noise, and reflection of acoustic waves to the acoustic detector and a subject due to air, and reducing the falling possibility while being worn. <P>SOLUTION: This component concentration measuring apparatus 11 is provided with an adsorbent body 12 adsorbed to the subject, a light source 13 emitting an intensity modulated light toward an adsorbent face of the adsorbent body 12, and the acoustic detector 14 detecting the acoustic waves generated from the subject 5 by the intensity modulated light emitted by the light source 13. This apparatus is characterized in fixing the acoustic detector 14 to the subject 5 by the adsorption of the adsorbent body 5. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
