Abstract:
1. A method of manufacturing a mirror, comprising: a first step of arranging, on a substrate, a shape adjusting layer having a layer thickness which changes by heat; a second step of arranging, on the shape adjusting layer, a reflection layer including a first layer, a second layer, and a barrier layer which is arranged between the first layer and the second layer, and prevents a diffusion of a material of the first layer and a material of the second layer; and a third step of bringing a shape of the reflection layer close to a target shape by changing a layer thickness profile of the shape adjusting layer after the second step, the third step including a process of partially annealing the shape adjusting layer, wherein the shape adjusting layer and the reflection layer each include corresponding adjustment positions, the adjustment positions being annealed portions of the shape adjusting layer and the reflection layer that are respectively thinner than non-annealed portions of the shape adjusting layer and the reflection layer after the process of the annealing.
