Abstract
Provided is an imaging lens, in which a space holding portion is formed outside the effective aperture of one or both of junction type compound lenses facing each other in order to hold the space between the junction type compound lenses. A mating face formed on the space holding portion which is made of the same material as that of a lens portion is brought in direct contact with a mating face provided on the other among the junction type compound lenses facing each other at the position facing the mating face of the space holding portion, outside the effective aperture of the other junction type compound lens. Alternatively, mating faces which are formed on confronting surfaces of the space holding portions formed on the facing junction type compound lenses are brought in direct contact with each other.
