A biological information measurement device includes a first light emitting portion that emits first light, a second light emitting portion that emits second light, a light receiving portion that receives the first light reflected by an epidermis of a skin, a dermis of the skin, and a subcutaneous layer, and the second light reflected by the epidermis and dermis of the skin, and a processing unit that calculates biological information by removing noise, from a first detection signal output based on the first light received by the light receiving portion, using a second detection signal output based on the second light received by the light receiving portion.
