shows lens data of example 1 in example 1 the central area diffractive structure has a seven level structure shown in fig6 a a first order diffracted light flux has a maximum diffraction light amount among diffracted light fluxes generated when the first light flux enters the central area diffractive structure a minus second order diffracted light flux has a maximum diffraction light amount among diffracted light fluxes generated when the second light flux enters the central area diffractive structure and a minus third order diffracted light flux has a maximum diffraction light amount among diffracted light fluxes generated when the third light flux enters the central area diffractive structure the intermediate area diffractive structure has a three level step structure shown in fig6 d a zeroth order diffracted light flux has a maximum diffraction light amount among diffracted light fluxes generated when the first light flux enters the intermediate area diffractive structure and a minus first order diffracted light flux has a maximum diffraction light amount among diffracted light fluxes generated when the second light flux enters the second basic structure the peripheral area diffractive structure may has any one of a blaze structure and a step structure and is a structure that a second order diffracted.
