PROBLEM TO BE SOLVED: To provide an imaging optical system, which can be reduced in size and thickness, with high productivity and an image photographing device incorporating it. SOLUTION: Related to the imaging optical system, a plurality of imaging units provided with a beam reflecting means 3 which makes an object plane 1 and an image plane almost parallel to each other are disposed in second dimension in the inter-object optical path of an imaging optical means that meets so-called Scheimpflug condition in which a titled object plane 1, an image plane 4, and a main flat plane of an optical system 2 cross each other at the same straight line B. It comprises a unit image plane on which focusing is made by dividing, one to one, to the number identical with the imaging units, for synthesizing the images of divided unit image planes.
