A solid-state imaging device including a semiconductor substrate including photoelectric conversion elements, and having color filters of plural colors formed on the semiconductor substrate and positioned in correspondence to the photoelectric conversion elements, a first visible-light transmissive layer formed between the semiconductor substrate and the color filters, and second visible-light transmissive layers each formed between adjacent color filters. The second visible-light transmissive layers include a same material as the first visible-light transmissive layer and are continuous with the first visible-light transmissive layer. The color filters having a largest area among the color filters of the plural colors each have an edge portion being continuous with an edge portion of a corresponding one of the second visible-light transmissive layers, and the color filters having the largest area each have a side wall on which a reaction product layer including a material forming the first visible-light transmissive layer is formed.
