The invention provides a novel optical sensor, an optical sensor unit, an optical sensor device and an information terminal device. This optical sensor is provided with: a wavelength filter that transmits light of a specific wavelength region; and a magnetic element provided with a first ferromagnetic layer, a second ferromagnetic layer, and a spacer layer sandwiched between the first ferromagnetic layer and the second ferromagnetic layer, the light having passed through the wavelength filter being irradiated on the magnetic element, and the light irradiated on the magnetic element being detected. 本发明提供一种新型的光传感器、光传感器单元、光传感器装置和信息终端装置。该光传感器具有：波长滤波器，其使特定的波长区域的光透过；和磁性元件，其具备第1铁磁性层、第2铁磁性层、和被所述第1铁磁性层和所述第2铁磁性层夹持的间隔层，透过了所述波长滤波器的光照射于所述磁性元件，对照射于所述磁性元件的光进行检测。
