A reflector in which the problem of deformation is significantly suppressed as compared with the prior art. A first glass plate having a first thickness and a first coefficient of thermal expansion, a reflective layer, an organic layer, and a second glass having a second thickness and a second coefficient of thermal expansion. A glass plate in this order, the first thickness is in the range of 0.1 mm to 1.0 mm, the second thickness is in the range of 2.5 mm to 4.0 mm, The first thermal expansion coefficient is in the range of 3 × 10 −6 / ° C. to 10 × 10 −6 / ° C., and the second thermal expansion coefficient is 3 × 10 −6 / ° C. to 10 × 10 − 6 / ° C., and the organic layer has a shear storage modulus of 0.5 MPa or less.
