Abstract
A projection lens, which is mounted on a housing of a projection device including an electro-optical element, includes a first holding part that holds a first optical system disposed along a first optical axis along which light emitted from the housing passes, a first reflective part that bends light parallel to the first optical axis to form light parallel to a second optical axis, a second reflective part that bends the light parallel to the second optical axis to form light parallel to a third optical axis, and a second holding part holds the first reflective part and the second reflective part. A distance along the first optical axis between a first lens, which is made of glass and is disposed to be closest to a reduction side in the first optical system, and the first reflective part is longer than a distance along the second optical axis between the first reflective part and the second reflective part. The first optical system includes an aspherical third lens that is made of a resin material and is disposed between the first lens and the first reflective part.
