PROBLEM TO BE SOLVED: To provide a pulse wave measuring instrument of a high measuring precision at a low cost. SOLUTION: This pulse wave measuring instrument is equipped with a pressure sensor for which a plurality of sensors having a wider range than a detailed sensor required for a conventional tonometry method are arranged. Then, from differencesαandβbetween an AI value based on a pulse wave signal from an applicable sensor directly above an artery, and an AI value based on a pulse wave signal from two sensor elements located by a predetermined distance from the first sensor element,α<SP>2</SP>+β<SP>2</SP>is acquired (S203), and an AI value correction amount is calculated by using a regression equation with the acquired value as a correction parameter indicating a strain degree (S205). By the correction amount, the AI based on the pulse wave signal from the applicable sensor directly above the artery is corrected (S207). COPYRIGHT: (C)2005,JPO&NCIPI
