Image pickup lens, image pickup module, method for manufacturing image pickup lens, and method for manufacturing image pickup module

An image pickup module comprising:

• an image pickup lens;
• and
• a solid-state image sensing device provided on an image surface of the image pickup lens,
• said image pickup lens including:
• an aperture stop;
• and
• a single lens,
• the aperture stop and the single lens being arranged in this order along a direction from an object to the image surface,
• the single lens being a meniscus lens having a concave surface facing the object,
• said image pickup lens satisfying formulas (1) and (2):
• 0.080<d1/d2<0.22 (1);
• and
• d1′/d1<1.00 (2)
• where:
• d1 is a center thickness of the single lens;
• d1′ is a thickness of a lateral side of the single lens;
• and
• d2 is a length in air between the image surface and a center of that surface of the single lens which faces the image surface.

• said method comprising the steps of:
• molding a molding material into a lens array, the lens array having portions each molded as the single lens;
• and
• dividing the lens array into separate image pickup lenses.
