1. A detecting device comprising:
a first light-emitting section configured to emit first light having a green wavelength band;
a second light-emitting section configured to emit second light having a wavelength band longer than the green wavelength band;
a first light-receiving section configured to receive the first light emitted from the first light-emitting section and emitted from a living body; and
a second light-receiving section configured to receive the second light emitted from the second light-emitting section and emitted from the living body, wherein
when a direction in which the first light-emitting section and the second light-emitting section are aligned is a first direction and a direction intersecting the first direction is a second direction,
in the second direction, at least a portion of the first light-receiving section is disposed closer to the first light-emitting section than the second light-receiving section,
a width of the first light-receiving section in the second direction is smaller than a width of the second light-receiving section in the second direction, a length of the first light-receiving section in the first direction is same as a length of the second light-receiving section in the first direction, and an area of the first light-receiving section is smaller than an area of the second light-receiving section.
