Abstract
A wavelength conversion element and a projector including the wavelength conversion element are provided, which have good heat dissipation performance. The wavelength conversion element includes a turntable, a wavelength conversion layer, and a porous structure. The turntable has a wavelength conversion region and a non-wavelength conversion region, and includes a central axis. The wavelength conversion layer is disposed in the wavelength conversion region of the turntable. The porous structure is disposed in the non-wavelength conversion region of the turntable, and a material of the porous structure includes foamed metal.
