1. A blood pressure measuring device, comprising:

  • a blood flow velocity sensor part for transmitting/receiving a wave motion with respect to a body surface of a subject to blood within the body, and detecting a blood flow within the body;

    a blood flow velocity sensor driving part for driving the blood flow velocity sensor part;

    a blood flow velocity sensor signal calculating part for controlling the blood flow velocity sensor driving part and the blood flow velocity sensor part, and obtaining a blood flow velocity within the body;

    a vascular diameter sensor part for transmitting/receiving ultrasound with respect to a blood vessel in the body, and detecting a difference in reflection arrival time for the vascular wall in the body;

    a vascular diameter sensor driving part for driving the vascular diameter sensor part;

    a vascular diameter sensor signal calculating part for controlling the vascular diameter sensor driving part and the vascular diameter sensor part, and obtaining the vascular diameter in the body; and

    a blood pressure signal calculating part for using a result of a calculation by the blood flow velocity sensor signal calculating part and the vascular diameter sensor signal calculating part to obtain a blood pressure of the subject.
