To provide a double eye imaging device capable of ensuring a visual field for each eye without making an imaging element large in size or reduced in the degree of freedom of imaging.
Respective eyes are composed of a front group 3 and a rear group 4, any one of the front group 3 and the rear group 4 is defined as a lens group having a positive refraction power and the other group is defined as a lens group having a negative refraction power. For each telescope eye P1 and each middle telescope eye P2, the lens group having the positive refraction power is disposed in the front group and the lens group having the negative refraction power is disposed in the rear group so that a length of each eye is shortened. For each wide angle eye P3, the lens group having the negative refraction power is disposed in the front group and the lens group having the positive refraction power is disposed in the rear group, so that a length of each eye is extended. Thus, the eyes are positioned closer to each other in the direction of optical axis on a first plane.
