PURPOSE:To prevent generation of a false signal by setting up a filter for separating a color formed onto a glass substrate while being brought into contact with a semiconductor substrate and making a distance between the end section of the glass substrate and a photoelectric converting section on the semiconductor substrate of a size larger than the thickness of the glass substrate. CONSTITUTION:A filter 3 for separating colors is formed brought into contact with the semiconductor substrate 2 having an image pickup function while being brought into contact with a case substrate 1, and a protective glass layer 4 is placed on an uppermost section. When light 8 projects to the side surface 9 of the glass substrate at an angle of theta, a distance L' of which light approaches to an effective picture element region on the semiconductor substrate is approximately equal to H' in an extent that the maximum angle of the incident angle theta is approximately 6 deg., and a refractive index n of glass is approximately 1.4 when the refractive index of glass is n and the height of glass through which light projects is H'. That is, it is necessary that the distance up to an effective picture element from the end section of the filter is brought to at least the height H or more of the filter. The false signal due to light incidence from the side surface 9 of the filter can be prevented by providing said allowance. |
