PROBLEM TO BE SOLVED: To provide a biological information detector that measures accurate biological information by reducing an amount of fluctuation in body motion noise even when a measurement state changes.SOLUTION: A biological information detector includes a first light receiving part 141, a second light receiving part 142, a third light receiving part 143, at least one light emitting part 150, a base plate 160, and a translucent member 50 that comes into contact with a subject when biological information on the subject is measured. When a distance between the light emitting part 150 and the second light receiving part 142 is represented by L2, and a distance between the light emitting part 150 and the third light receiving part 143 is represented by L3, the relationship of L3>L2 is satisfied. When distances from the base plate 160 to the surface of the translucent member 50 that comes into contact with the subject in areas where the translucent member 50 overlaps the first light receiving part 141, the second light receiving part 142, and the third light receiving part 143 in a plane view in a direction DR1 from the biological information detector to the subject are represented by h1, h2, and h3 respectively, the relationship of h1>h2 and h1>h3 is satisfied.SELECTED DRAWING: Figure 3 |
