A physiological information measuring apparatus includes a first detection unit, having a first light emitting unit and a first light receiving unit, separated from one another by a first distance. A second detection unit of the physiological information measuring apparatus has a second light emitting unit and a second light receiving unit, separated from one another by a second, different distance. Alternatively, the second detection unit shares the first light emitting unit with the first detection unit and has a second light receiving unit. Alternatively, the second detection unit shares the first light receiving unit with the first detection unit and has a second light emitting unit. A measuring unit of the physiological information measuring apparatus measures the physiological information of a user based on light received by the light receiving unit or light receiving units.
