PROBLEM TO BE SOLVED: To provide a mold for forming an on-chip lens capable of materializing the highly accurate registration in light condensation and to provide a solid-state image pickup element having high light condensation efficiency using the mold for forming the on-chip lens. SOLUTION: The mold apparatus for forming an on-chip lens is provided with the wall parts 102 that are installed so as to rise in the areas between each lens in accordance with the lens surface forming pitch of the on-chip lens, substrates 104 that are installed on the upper layers of the wall parts and have concave surfaces having a desired curvature in each area enclosed by the wall parts, and a coating layer 105 that is formed so as to cover the concave surfaces of the substrates.
