SOLID-STATE IMAGING ELEMENT

摘要

Provided is a solid-state imaging element capable of implementing a thin-film color filter which implements the filter characteristics of human visual sensitivity without reducing luminance signals, and the solid-state imaging element is provided with a plurality of two-dimensionally arranged light receiving portions (102), and color filters which are arranged on the respective plurality of light receiving portions (102), and which have different light absorption characteristics from one another, wherein a plurality of the color filters include a first color filter (108) having a transmission center wavelength in a blue color region, a second color filter (109) having the transmission center wavelength in a green color region, and a third color filter (110) comprising a first transmission band having the transmission center wavelength in a red color region, and a second transmission band having the transmission center wavelength in the blue color region, and wherein the third color filter (110) is configured from a medium, the permittivity of which is greater than 1 but lower than 5, and metallic fine particles having an average particle diameter of not more than 100 nm, which are dispersed in the medium.
