The present invention relates to a blood pressure measurement apparatus comprising: an input unit where at least one value selected from the maximum applied pressure, which is the applied pressure at which the maximum pulse pressure is attained during the pulse pressure measurement at the measurement part, the maximum pulse pressure, which is the pulse pressure at the maximum applied pressure, the depth of blood vessel at the measurement part measured by a pressure sensor, the elasticity of skin tissue at the measurement part and the elasticity of blood vessel at the measurement part is inputted； and a mean arterial pressure calculation unit where the mean arterial pressure is calculated from the input values of the maximum applied pressure, the depth of blood vessel and the elasticity of skin tissue. The present invention offers more effective and reliable blood pressure measurement apparatus.
