Abstract
The imaging apparatuscomprises: a semiconductor imaging devicewhich converts incident light to an electrical signal; an optical filterwhich is opposed to an incident surface of the semiconductor imaging deviceand transmits light of a certain wavelength; and a three-dimensional substratefixing the optical filterby means of adhesion using a filler-containing adhesivewherein the diameter of the filler is smaller than or equal to the pixel size of the semiconductor imaging device. Degradation of image quality of the imaging apparatuscaused by the dropped filler can thus be reduced.
