A first central principal ray Lc1 of a first light beam L1 that has passed through a first front group Gf1 passes through a back first group Gb1, a first aperture center CS1, a first deflection group Gv1, and a back second group Gb2 at a position separated from a back group central axis Cb and reaches a image plane I, and a second central principal ray Lc2 of a second light beam L2 that has passed through a second front group Gf2 passes through the back first group Gb1, a second aperture center CS2, a second deflection group Gv2, and the back second group Gb2 at a position separated from the back group central axis Cb and reaches the image plane I.
