PROBLEM TO BE SOLVED: To obtain a high quality image by increasing the light collection efficiency of an image pickup device in an image pickup apparatus having a photographing lens having a zooming function or a focus adjustment function. SOLUTION: Each solid-state imaging device is a photoelectric conversion device (31) for converting incident light (60) into an electric signal, a microlens (902), and resin, any one of titanium oxide, silicon nitride, and niobium pentoxide. An image sensor comprising an optical waveguide (36) made of a composite material in which is dispersed, and an interlayer insulating layer (38) made of hydrophobic porous silica, and a plurality of the solid-state image sensors arranged in two dimensions is mounted. The distance from the exit pupil of the imaging device to the photoelectric conversion element is L, the distance from the center of the image sensor to the position of the solid-state imaging element is H, the height from the photoelectric conversion element to the apex of the microlens is D, and When the interval between the plurality of solid-state imaging devices is P, the refractive index of the optical waveguide is N H , and the refractive index of the interlayer insulating layer is N L , the solid-state imaging device positioned at the distance (H) is However, 0 <a <1 is satisfied.
