Abstract: <P>PROBLEM TO BE SOLVED: To provide a pressure pulse wave detector which can judge whether or not the form of a pressure pulse wave is exact.  <P>SOLUTION: A pulse pressure PP of the pressure pulse wave detected by a pressure pulse wave sensor 54 is calculated by a pulse pressure calculating means 90, maximum blood pressure value and a minimum blood pressure value are determined by a blood pressure value determining means 82 for determining the blood pressure values by using a cuff 12, and a blood pressure difference ΔBP as a difference between the maximum blood pressure value and the minimum blood pressure value is calculated by a blood pressure difference calculating means 92.
