PROBLEM TO BE SOLVED: To provide a projector and lens array able to minimize a level difference in each boundary portion between element lenses in the entire lens array and also able to ensure uniform bright illumination.SOLUTION: One second element lens E43 disposed in the central area AR1 of a second lens array 24 has a shape different from one or more second element lenses E33, E34, E44, E54, E53, E52, E42, and E32 arranged adjacent to one another, and has a plurality of boundaries B1, B2, B3, B4, B5, B6, B7, and B8 formed between the one second element lens E43 and the second element lenses B1, B2, B3, B4, B5, B6, B7, and B8. The outline of the second element lens E43 is octagonal as viewed from a direction parallel to an optical axis. |
