Abstract

In a solid image pickup device, a plurality of microlenses are provided on a substrate having light receiving portions in opposition to the light receiving portions so that incident light can converge onto the light receiving portions. The microlenses are covered with a transparent resin layer having a refractive index smaller than that of the microlenses. Therefore, the solid image pickup device, even when packaged in a molded body made of a resin having a refractive index similar to that of the microlenses, can realize good sensitivity because the microlenses can effectively operate as condenser lenses due to the resin layer between the molded body and the microlenses.
