A conventional solid-state imaging device in which a sealing resin is applied onto a microlens has a low condensing efficiency. There are provided a photodiode 14 for receiving light, a microlens 4 made of a resin set on the photodiode 14 and having a refractive index of n3, a thin-film lens 3 formed on the microlens 4 and having a refractive index of n2, a sealing resin 2 formed on the thin-film lens 3 and having a refractive index of n1, and cover glass 1 formed on the sealing resin 2 to seal the sealing resin 2. The refractive index n2 of the thin-film lens 3 is set to a value smaller than n1 and n3. In this case, it is assumed that values of n1 and n3 are substantially equal to each other and the thin-film lens 3 is made of fluoride and/or oxide.
