• Gravitational lensing effect on infrared number counts is a useful tool for the studyof galaxy evolution at high redshift. In contrast to the case of optical number counts, far infrarednumber counts are enhanced by the existence of gravitational lens. We introduce the concept of themagnification bias and then formulate the gravitationally lensed number count of infrared galaxies.Then we show the possibility of utilizing the lensed number counts of the infrared galaxies as atool for the study of galaxy evolution.
