PROBLEM TO BE SOLVED: To provide an imaging apparatus whose imaging efficiency at an image pickup element is improved.SOLUTION: An optical fiber 3c has a core part 3co and a clad part 3cl. The diameter of the core part 3co of a light emitting surface 3cb of the optical fiber 3c is larger than the diameter of the core part 3co of a light incident surface 3ca of the optical fiber 3c. Optical fibers 3c away from an optical axis AX of the imaging optical system 2 satisfy a specific formula. |
