PROBLEM TO BE SOLVED: To provide an imaging apparatus having simple structure that can obtain appropriate information about living body tissue for a wide range in the depth direction thereof. SOLUTION: The imaging apparatus includes an image formation optical system 20 that forms an image of the living body tissue 31 illuminated with a light L including wavelength components that are different from each other, and an imaging means 23 that images the living body tissue 31. The image formation optical system 20 has axial chromatic aberration in which focal length for C line (a wavelength of 643.8 nm) is greater than or equal to 102 when focal length for F line (a wavelength of 486.1 nm) is regarded as 100.
