The invention provides a novel light detection element. This optical detection element is provided with a magnetic element having a first ferromagnetic layer, a second ferromagnetic layer, and a spacer layer sandwiched between the first ferromagnetic layer and the second ferromagnetic layer, and an optical waveguide formed from at least a core and a cladding layer covering at least a portion of the core. The light propagating through the optical waveguide irradiates the magnetic element. 本发明提供一种新的光检测元件。该光检测元件具备磁性元件和光波导，所述磁性元件具有第一铁磁性层、第二铁磁性层、被所述第一铁磁性层和所述第二铁磁性层夹持的间隔层，所述光波导至少由芯和包覆所述芯的至少一部分的包层形成，在所述光波导中传播的光向所述磁性元件照射。
