<p>Provided are a small imaging lens which ensures a wide field angle, permits various aberrations to be excellently corrected and is applicable to an imaging element having a high pixel density, an imaging device using such imaging lens, and a portable terminal using such imaging device. The imaging lens is configured by sequentially having, from the object side, an aperture stop, a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a positive refractive power and a fourth lens having a negative refractive power, and the imaging lens is designed to satisfy a prescribed conditional expression.</p> |
