A reading lens for a scanner to read an original in a reduced magnification, the lens comprising six lenses, i.e., from a first lens to a sixth lens in order on an optical axis. The first lens is a positive lens having a first lens-surface and a second lens-surface. The second lens is a negative lens disposed in contact with the first lens and has the second lens-surface in common with the first lens and a third lens-surface. The third lens is a meniscus lens and has a fourth lens-surface and a fifth lens-surface. The fourth lens is a meniscus lens and has a sixth lens-surface and a seventh lens-surface. The fifth lens is a negative lens and has a eighth lens-surface and a ninth lens-surface. The sixth lens is a positive lens disposed in contact with the fifth lens and has the ninth lens-surface in common with the fifth lens and a tenth lens-surface. At least one of the ten lens-surfaces is formed as an aspherical surface.
