An optical sensor includes a wavelength filter configured to transmit light in a specific wavelength range and a magnetic element including 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 passing through the wavelength filter is applied to the magnetic element and the light applied to the magnetic element is detected.
