A sphygmomanometer(1)in advance memorizes parameters for calculating a blood pressure value from a measured value in a state of removing clothes from a measurement part and a measured value with clothes on. The blood pressure value is calculated by using the above-mentioned parameter memorized with respect to the measured value while a clothed mode is selected with button(3-4) at sphygmomanometry.血壓計(1)係預先由在從測定部位除去衣服之狀態下的測定值和穿著衣服時的測定值中,記憶用以從穿著衣服時之測定值算出血壓值的參數。在測定血壓時,若以按鈕(3-4)選擇有衣服模式,使用對測定值所記憶之上述參數來算出血壓值。1‧‧‧血壓計2‧‧‧本體3‧‧‧操作部3-1~3-5‧‧‧按鈕4‧‧‧顯示器5‧‧‧腕帶10‧‧‧空氣管
