Abstract
A biological information detecting device includes: a first light receiving portion and a second light receiving portion which receive light from a subject; a processing portion; and at least one light emitting portion (light emitting portion or the like) which emits light to the subject. When a distance between the light emitting portion and the first light receiving portion is set to Land a distance between the light emitting portion and the second light receiving portion is set to L, L<Lis satisfied. The processing portion performs body motion noise reduction processing that reduces a body motion noise of a first detection signal which is detected by the first light receiving portion based on a second detection signal which is detected by the second light receiving portion, and calculates biological information based on the first detection signal after the body motion noise reduction processing.
