1. A blood pressure detection apparatus comprising:

  • a press mechanism that applies pressure to a blood vessel by pressing a living body, and can gradually decrease the pressure;

    a pressure sensor that detects a change in pressure of the blood vessel caused by a change in the pressure applied by the press mechanism; and

    a blood pressure calculation section that determines the pressure applied by the press mechanism when a given waveform pattern appears in a waveform that indicates a change in pressure of the blood vessel to be a maximal blood pressure, determines the pressure applied by the press mechanism when the waveform has a maximum amplitude to be a mean blood pressure, and calculates a minimal blood pressure using the maximal blood pressure and the mean blood pressure.
