<P>PROBLEM TO BE SOLVED: To miniaturize an imaging device capable of illuminating a light having an intensity covering a desired range. <P>SOLUTION: This biological information acquisition device 50 acquires biological information of a subject based on light illumination to the subject. This biological information acquisition device 50 is provided with a light source 6 for emitting a light to be illuminated to the subject, a light guide plate 3 for guiding an outgoing light from the light source to the subject, a light receiving element having a plurality of pixels for receiving a light entering from the subject via the light guide member. The pixels of the light receiving element receive the incident light entering therein from the subject side via the light guide member. The disposition relationship between the light guide member and the light receiving element is thus set so as to provide this biological information acquisition device capable of illuminating the light having the intensity covering a desired range without enlarging the device. <P>COPYRIGHT: (C)2009,JPO&INPIT |
