PROBLEM TO BE SOLVED: To provide a reflection type imaging optical element that can be easily manufactured and displays a real image of an observation target in the air. ! SOLUTION: An imaging optical element includes: an optical element S1 that has a function to arrange V-groove shapes having a substantially right angle in one direction at constant intervals and use the surfaces of the V-grooves as a reflection surface, so as to collect incident light on a straight line through the reflection twice on the V-grooves mentioned above; and an optical element S2 that has a refractive power only in one direction and has a function to collect incident light on a straight line. The optical element S1 and optical element S2 has a transparent medium filling the space therebetween, and are arranged to have the light collection direction of a surface 1 and the light collection direction of a surface 2 to be substantially orthogonal to each other. !
