Abstract
A solid-state imaging device includes: a substrate; a photo-receiving portion formed in the substrate; a wiring layer formed on the substrate and having a trench being formed on a region directly above the photo-receiving portion; and a light guiding member provided in the trench and made of organic material. An empty space is formed between a side wall of the trench and a side surface of the light guiding member. The side surface of the light guiding member is curved so that a central part of the side surface along a vertical direction is closer to a center axis of the trench than both end parts of the side surface along the vertical direction.
