A method for manufacturing a diffractive multi-focal ophthalmic lens capable of generating at least three focal points in an optical axis direction using a diffractive structure comprising a plurality of zones in a concentric circle form, the method comprising the following steps: generating a composite profile by overlapping at least two starting profiles comprising a plurality of zones in a concentric circle form; generating an adjusted profile by adjusting phase or adjusting phase and amplitude of zones of the composite profile as a subject in order to set an intensity distribution in the optical axis direction and determine optical characteristics; and manufacturing the diffractive multi-focal ophthalmic lens for which the adjusted profile is provided in at least a portion of the diffractive structure, characterized in that the at least two starting profiles all have a phase expressed as a blaze shaped function in relation to a lens radial distance in at least a portion of a region overlapped, and the phase of the composite profile is also expressed as a blaze shaped function, the blaze shaped function of the composite profile is expressed by Equation 1, adjustment of the phase of the zones of the composite profile as the subject is performed by varying both of a phase constant h expressed by Equation 2 using φ i and φ i-1 of Equation 1, and a phase shift τ of Equation 1, and when adjusting the phase of the composite profile, the adjusted profile is set so as to include the zones for which the phase constant h changes periodically in a radial direction while the adjusted profile is set so as to include the zones for which the phase shift τ changes periodically in a radial direction φ r = φ i − φ i − 1 r i − r i − 1 × r + φ i − 1 × r i − φ i × r i − 1 r i − r i − 1 + τ r: Radial distance from the lens center r i-1: Inner diameter of the ith zone (radius) n: Outer diameter of the ith zone (radius) φ i-1: Phase at the inner diameter (radius) position of the ith zone φ i: Phase at the outer diameter (radius) position of the ith zone τ: Phase shift h = φ i − 1 − φ i 2 π. generating a composite profile by overlapping at least two starting profiles comprising a plurality of zones in a concentric circle form; generating an adjusted profile by adjusting phase or adjusting phase and amplitude of zones of the composite profile as a subject in order to set an intensity distribution in the optical axis direction and determine optical characteristics; and manufacturing the diffractive multi-focal ophthalmic lens for which the adjusted profile is provided in at least a portion of the diffractive structure, characterized in that the at least two starting profiles all have a phase expressed as a blaze shaped function in relation to a lens radial distance in at least a portion of a region overlapped, and the phase of the composite profile is also expressed as a blaze shaped function, the blaze shaped function of the composite profile is expressed by Equation 1, adjustment of the phase of the zones of the composite profile as the subject is performed by varying both of a phase constant h expressed by Equation 2 using φ i and φ i-1 of Equation 1, and a phase shift τ of Equation 1, and when adjusting the phase of the composite profile, the adjusted profile is set so as to include the zones for which the phase constant h changes periodically in a radial direction while the adjusted profile is set so as to include the zones for which the phase shift τ changes periodically in a radial direction φ r = φ i − φ i − 1 r i − r i − 1 × r + φ i − 1 × r i − φ i × r i − 1 r i − r i − 1 + τ r: Radial distance from the lens center r i-1: Inner diameter of the ith zone (radius) n: Outer diameter of the ith zone (radius) φ i-1: Phase at the inner diameter (radius) position of the ith zone φ i: Phase at the outer diameter (radius) position of the ith zone τ: Phase shift h = φ i − 1 − φ i 2 π. r: Radial distance from the lens center r i-1: Inner diameter of the ith zone (radius) n: Outer diameter of the ith zone (radius) φ i-1: Phase at the inner diameter (radius) position of the ith zone φ i: Phase at the outer diameter (radius) position of the ith zone τ: Phase shift
