<p>A method for producing an optical part provided with composition ratio distributions, including a refractive index distribution, in an order of mm is provided. The method includes an irradiation process for irradiating a radiation-sensitive polymerizable composition (1) with a radiation (5). The composition (1) includes at least a polymerizable compound (a) and a polymerizable or non-polymerizable component (c). The irradiation process includes at least a first step of irradiating with a radiation (5) only a first irradiation region that is a portion of the composition (1) and a second step of irradiating with a radiation (5) only a second irradiation region that is a portion of the composition (1) and is different from the first irradiation region in at least one of size and position. When the component (c) is polymerizable, the polymerization rate of the component (c) is lower than that of the compound (a) in the first and the second steps.</p> |
