PROBLEM TO BE SOLVED: To provide an imaging element array with reduced number of components.SOLUTION: In an imaging element array 1 formed by arranging a plurality of imaging elements 10, a light beam l is made incident from an object surface 16 to an incident lens surface 13, and is reflected toward a second reflection surface 22 by a first reflection surface 21 having positive refractive power in an arrangement direction X. Between a reflection surface front group and reflection surface rear group (between the first reflection surface 21 and the second reflection surface 22), an inverted image (intermediate image i) in the arrangement direction X is formed. The light beam l reflected by the second reflection surface 22 exits from the exit lens surface 15 to an image plane 17, to form an inverted image of the intermediate image i (inverted image of an object) in the arrangement direction X. The exit lens surface 15, the incident lens surface 13, the first reflection surface 21, and the second reflection surface 22 are formed on each predetermined surface of a transparent body 11. There is no need for two lens arrays facing each other, thereby reducing the number of components. |
