Abstract: This light detection element includes a meta-lens that includes nanostructures which are two-dimensionally arranged; and a magnetic element that includes a first ferromagnetic layer, a second ferromagnetic layer, and a spacer layer sandwiched between the first ferromagnetic layer and the second ferromagnetic layer. Light which passes through the meta-lens is applied to the magnetic element.
