A solid-state image sensor prevents shading while maintaining the wide dynamic range of an image signal without reducing its resolution. The image sensor has its photodiode array including arrangement patterns, each of which includes a smaller micro-lens and larger micro-lenses arranged on the top, bottom, right and left sides of the smaller micro-lens in a first virtual plane formed by the array. When the arrangement pattern is viewed in parallel to the virtual plane through a gap between the larger micro-lenses positioned on the bottom and left sides of the smaller micro-lens in the plane, the image of an unhidden part of the smaller micro-lens visible through the gap is, at most, half as much in area as the whole image of the smaller micro-lens projected on a second virtual plane perpendicular to the first virtual plane.
