PROBLEM TO BE SOLVED: To provide a biological information measurement system, where the time required for the output of measurement results is shortened and the measurement of biological information corresponding to each subject is available.SOLUTION: A blood pressure meter 10 includes a measurement part 21 to measure the biological information of a subject, a calculation part 22 to calculate using the measured biological information, and an output part 23 to output the measurement results for biological information based on the calculation results by the calculation part 22. The blood pressure meter 10 also includes a measurement start instructor 24 to instruct the measurement part 21 in starting the measurement of biological information, and an individual identification part 25 to identify the subject. The measurement of biological information by the measurement part 21 and the identification of the subject by the individual identifier 25 are done in parallel based on the measurement start instruction given by the instructor 24. The measurement mode of measurement part 21, the calculation mode of calculator 22 and the output mode of output part 23 are changed based on the information of each subject obtained by the individual identification part 25.
