To provide an inverted Galilean finger for film unit with lens having excellent recyclability at a low cost without degrading the optical performance.

An objective lens 31 and an eyepiece 32 are molded from the same resin as the resin of a main body base part to which these lenses are assembled. A lens 31b on the image side of the objective lens 31 is formed in a concave aspherical surface and at least either of lens faces 32a and 32b of the eyepiece 32 are formed in an aspherical surface. When the focal length of the objective lens 31 is f1 and the focal length of the eyepiece 32 f2, the lenses satisfy conditions '0.4<f1/f2<0.7'. The objective lens 31 and the eyepiece 32 can be recycled integrally with the main body base part and can be manufactured more inexpensively than the conventional finders using a costly methacrylic resin. The balance of various aberrations may be maintained at a good state by adopting the aspherical surfaces to the objective lens 31 and the eyepiece 32.
