Claim:
1. An image sensor, comprising: first and second photoelectric conversion elements formed in a first pixel and a second pixel of a substrate, respectively; a first pixel lens formed over the first photoelectric conversion element of the first pixel and comprising a first lower light condensing layer and a first upper light condensing layer, wherein the first upper light condensing layer has a smaller width than the first lower light condensing layer and is formed over the first lower light condensing layer; a first color filter covering the first pixel lens and filtering a visible ray of a first wavelength band; a second pixel lens formed over the second photoelectric conversion element of the second pixel and comprising a second lower light condensing layer and a second upper light condensing layer, wherein the second upper light condensing layer has a smaller width than the second lower light condensing layer and is formed over the second lower light condensing layer, wherein the second pixel lens has a width different from a width of the first pixel lens; and a second color filter covering the second pixel lens and filtering a visible ray of a second wavelength band longer than the first wavelength band.
