Projection lens with a first optical system to form an intermediate image of an optical image and projection device

A projection lens that is mounted on a housing of a projection device including an electro-optical element, the projection lens comprising:

• 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 that holds the first reflective part and the second reflective part,
• wherein a distance along the first optical axis between a first lens, which 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 a second lens that is disposed to be closest to an enlargement side of the first optical system at an immediate upstream of the first reflective part at a reduction side thereof to form an intermediate image of an optical image of the electro-optical element between the second lens and the first reflective part,
• the first lens is a lens made of glass, and
• the first optical system includes an aspherical third lens that is made of a resin material and is disposed to be closer to the reduction side than the second lens.
