Summary:Provided is an imaging lens using a wafer scale lens which can easily be produced in a mass production. The entire optical length can be reduced without increasing a lens substrate or a lens formed on the substrate or without using a diffracting plane. The aberration can be preferably corrected. The imaging lens forms a first lens having a positive refractive power and Abbe number W1 on the object side and a second lens having a negative refractive power and Abbe number W2 on the image side of the first lens substrate. The difference between the Abbe number W1 and the Abbe number W2 (W1-W2) is set to be a value greater than 10.
