A hybrid achromatic optical lens having a high numerical aperture whose chromatic aberration is removed and a method for manufacturing the same are provided. The hybrid achromatic optical lens includes a first optical member of a low index of refraction and a second optical member of a high index of refraction. The second optical member is formed on a depressed portion of the first optical member and has a diffractive surface, which is a contact surface of the second optical member with the first optical member and has a plurality of pitches formed on a refractive surface. The method for manufacturing the hybrid achromatic optical lens includes forming a profile of a diffractive surface having a plurality of pitches on a molding die whose one surface is the same as a profile of a refractive surface, forming a depression having the diffractive surface on a first optical member having a low index of refraction using the molding die, and coating a material having a high index of refraction on the depression, grinding a surface of material, and forming a second optical member having a high index of refraction.
