PROBLEM TO BE SOLVED: To provide a biological information detector which detects signals with different characteristics while having a certain degree of correlation in each of a plurality of light reception parts by including a proper structure, and provide an electronic apparatus and the like.SOLUTION: A biological information detection device comprises: a first light reception part 140 which receives light from a subject a second light reception part 141 and a translucent member 50 which is provided at the position on the subject side with respect to the first light reception part 140 and the second light reception part 141, transmits light from the subject, and is brought into contact with the subject to apply pressure thereto at the time of measuring the biological information of the subject. When the height of the translucent member 50 at the position or in the region corresponding to the first light reception part 140 is defined as h1 and the height of the translucent member 50 at the position or in the region corresponding to the second light reception part 141 is defined as h2 in the direction from the biological information detector to the subject, h1 and h2 satisfy h1>h2.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT
