An information-reading element may be provided, which can be made small, and allows the number of adjustment steps to be reduced, and an information-reading device may be provided. An information-reading element may be provided and equipped with a light-emitting element, which serves as a polarized light-emitting part for emitting polarized light as outgoing light, and a light-receiving element, which serves as a polarized light-receiving part for receiving the polarized light as returning light after the polarized light is reflected off a reflecting plate, said reflecting plate being a target object from which information is to be read, wherein the light-emitting element and the light-receiving element have different polarization characteristics from each other.
