A biological information detector includes a light-emitting part, a light-receiving part, a reflecting part, and a substrate. The light-receiving part is for receiving light having biological information, where the light is emitted by the light-emitting part and reflected at a detection site of a test subject. The reflecting part is for reflecting the light emitted by the light-emitting part or the light having biological information. The substrate has a first surface and a second surface facing the first surface, formed from a material that is transparent with respect to a wavelength of the light emitted by the light-emitting part, at least one of the first surface and the second surface of the substrate has a light-blocking region containing wiring leading to at least the other of the light-emitting part and the light-receiving part.
