PROBLEM TO BE SOLVED: To provide an imaging apparatus in which the mounting accuracy of optical members is improved and air bubbles contained in the adhesive agent and surplus adhesive agent are discharged at a low cost.SOLUTION: First and second optical members, which are adjacent to each other among a plurality of optical members of the imaging apparatus, are adhered by way of an adhesive layer. In the spaces between the first and the second optical members are arranged spacers which make the gaps between the first and the second optical members uniform and which has such a structure that at least one side of a light transmission area is opened, the light transmission area being in a space through which subject light received in the effective pixel area of an image pickup device is passed and being projected with a rectangular effective pixel area of the image pickup device.COPYRIGHT: (C)2016,JPO&INPIT
