Abstract
An object of the present invention is to provide a solid-state imaging device that can be slimmed down and have an improved picture quality without sacrificing its sensitivity and the manufacturing method of the solid-state imaging device. The solid-state imaging device includes an imaging unit where unit cells are arranged in a two-dimensional array. Each of these unit cells has a photodiode and a first microlens and a second microlens which are formed above the photodiode. The maximum curvatures of the convex parts become greater from the center part to the periphery of the imaging unit.
