A biological information measurement device includes: a sensor module (20) which includes N light-emitting elements (21) (N is an integer greater than or equal to 3) which emit light having different wavelengths and N-1 light-receiving elements (22) which receive the light having different wavelengths emitted from the light-emitting elements (21) and reflected by an organism (10) and which output a signal of an intensity corresponding to an amount of light to be received, and a signal processing unit which performs signal processing on an output signal from the light-receiving elements (22) and which generates biological information, wherein the signal processing unit includes a microcontroller which controls an amount of light to be emitted of each of the light-emitting elements (21) on the basis of an intensity of an output signal from each of the light-receiving elements (22).
