Provided is a living-body information measurement device including a first light emitting element and a second light emitting element each that emits different light in wavelength, a light receiving element that receives the light emitted from the first and second light emitting elements and outputs a received light signal corresponding to an amount of the received light, a separation unit that separates the received light signal into a first received light signal and a second received light signal, a filter that removes noise components of the first received light signal and the second received light signal, and a measuring unit that measures plural living-body information using the first received light signal before the noise components are removed by the filter, the first received light signal whose noise components are removed by the filter, and the second received light signal whose noise components are removed by the filter.
