Abstract: A biosignal sensor includes a substrate, first light-emitting elements, second light-emitting elements, and light-receiving elements. The light-receiving elements are positioned individually spaced apart by different distances from the first light-emitting elements and the second light-emitting elements and receive light from the first light-emitting elements and the second light-emitting elements. The plurality of light-receiving elements are linearly or substantially linearly aligned in an X direction. The first light-emitting elements and the second light-emitting elements are located at positions different in a Y direction from positions of the plurality of light-receiving elements.

Abstract: A sensing device is provided that includes a non-flexible body that is wearable on a user's finger and a biosensor that measures biological information through the finger. The body has an inner peripheral surface facing a pad, a back, an outer side surface, and an inner side surface. The biosensor is on the inner peripheral surface to face the pad when the body is worn on the finger. In a cross-section of the inner peripheral surface, a first distance between a portion of the inner peripheral surface that faces the pad of the finger and a portion of the inner peripheral surface that faces the back of the finger is shorter than a second distance between a portion of the inner peripheral surface that faces the outer side surface of the finger and a portion of the inner peripheral surface that faces the inner side surface of the finger.
