IMAGING DEVICE AND ELECTRONIC APPARATUS

An imaging device includes: a beam splitter having a light incident surface on which light from an object is incident; a reflection mirror for returning light transmitted through the beam splitter to the beam splitter side; a first imaging part including a first lens, the first imaging part being arranged on a first emission surface side of the beam splitter in which the light from the light incident surface side is reflected and emitted; and a second imaging part including a second lens, the second imaging part being arranged on a second emission surface side of the beam splitter in which the light from the reflection mirror side is reflected and emitted. An optical distance of the light from the light incident surface to the first lens is set to be substantially equal to an optical distance of the light from the light incident surface to the second lens.
