Abstract
A solid-state imaging device is provided which includes an optical low-pass filter, and a solid-state imaging element chip for receiving optical signals through the low-pass filter. In addition, a shielding member having an optical transmissivity and an electric conductivity is interposed between the low-pass filter and the solid-state imaging element chip to improve image quality.
