An image pickup lens unit includes, as viewed from an object side, a retainer having an aperture stop, an image pickup lens, and a holder. The retainer having an aperture stop and the image pickup lens are united with each other. The holder assumes a substantially cylindrical shape and accommodates the image pickup lens such that the image pickup lens is united with the holder in a manner movable in relation to the holder, whereby movement of the retainer having an aperture stop causes the image pickup lens to move in relation to the holder to thereby carry out focus adjustment.
