A biometric information measuring apparatus includes a light emitting unit, a light receiving unit, a detecting unit and a controller. The light emitting unit is configured to emit light. The light receiving unit is configured to receive light. The detecting unit is configured to detect a frequency distribution of the light received by the light receiving unit. When a feature which is obtained in response to a living body being irradiated with light is included in the frequency distribution detected by the detecting unit, the controller controls an operation state of the apparatus to switch from a standby state to a measurement state in which biometric information in the living body is measured.
