A biometric information detecting apparatus is provided. The biometric information detecting apparatus includes a fixing unit disposed on a lower structure, and a pressure pulse wave measuring unit that is supported by the fixing unit and separate from the lower structure. An optical pulse wave measuring unit is disposed on the pressure pulse wave measuring unit. The optical pulse wave measuring unit may contact a surface of a subjects body. A pressure pulse wave of the subjects body may be measured by the pressure pulse wave measuring unit and an optical pulse wave of the subjects body may be measured by the optical pulse wave measuring unit, at the same time.
