Abstract
A finder optical system includes a display element and a diffractive optical element that is disposed on an eye point side of the display element so as to continue from the display element. The diffractive optical element includes a first base, a first layer that is laminated on the first base and includes a first diffractive optical surface on a surface thereof opposite to the first base, a second base, and a second layer that is laminated on the second base and includes a second diffractive optical surface on a surface thereof opposite to the second base. The first diffractive optical surface and the second diffractive optical surface are in close contact with each other.

A finder optical system comprising:
- a display element;
- and
- a diffractive optical element that is disposed on an eye point side of the display element so as to continue from the display element,
- wherein the diffractive optical element consists of, a first base, a first layer that is laminated on the first base and that includes a first diffractive optical surface on a surface thereof opposite to the first base, a second base, and a second layer that is laminated on the second base and that includes a second diffractive optical surface on a surface thereof opposite to the second base,
- the first layer and the second layer are disposed so as to face each other, and
- the first diffractive optical surface and the second diffractive optical surface are in contact with each other within the diffractive optical element.
