A solid-state imaging device capable of making reduction in reflection at the interface between a light guide and an incident unit consistent with improvement in condensing efficiency by the light guide is provided. The solid-state imaging device includes a substrate internally including a photoelectric conversion unit, and a condensing unit provided on an optical incident side of the substrate. A configuration satisfying relationships of |N1|<|√∈×√μ| and 0.63<N1/(√∈/√μ)<1.58 on an end face of the optical incident side of the condensing unit is adopted. Here, N1 is a refractive index of a medium forming a region of the optical incident side of the condensing unit, and ∈ is a specific permittivity of a medium forming the condensing unit, and μ is a specific permeability of the medium forming the condensing unit.
