A biometric-information measuring electrode includes a conductive bundle including a plurality of conductive wires and having a distal end which is one end and a rear end which is another end, a terminal electrically connected to the conductive bundle, a support portion located adjacent to the distal end of the conductive bundle and movably supporting the conductive bundle, and a protrusion mechanism (a first protrusion mechanism) configured to protrude the conductive bundle toward the distal end. The distal end of the conductive bundle is capable of coming into contact with a living organism. The support portion keeps a relative position of the conductive bundle to the terminal in a state in which the protrusion mechanism is not performing an operation to protrude the conductive bundle. This allows the electrode to be repeatedly used even if the electrode is soiled.
