PROBLEM TO BE SOLVED: To provide a solid-state image sensing device improving an image quality by inhibiting the reflection of an unnecessary light generated on the internal surface of the side wall of a main body constituting a package and an optical apparatus with the solid-state image sensing device. SOLUTION: A photodetector 11 is arranged vertically to an optical axis L, and outputs an electric signal corresponding to the quantity of an incident light. The package 2a for protecting the photodetector 11 has a main body 3a, to which a recess for arranging the photodetector 11 is formed, and a cover 4 being arranged in the opening of the main body 3a and having a light transmission property. The main body 3a is constituted so as to inhibit a light necessary to shield the reflection, and prevent the incidence of the unnecessary light to the photodetector 11. To be concrete, when a shortest distance between the end of the photodetector 11 and the internal surface 5 of the side wall of the recess is represented by d1 and a distance between the photodetector 11 and the cover 4 by d2, a value d1/d2 obtained by dividing d1 by d2 is set at a value larger than 10 and less than 1,000.
