In an electronic blood pressure meter (1), a CPU (40) causes operation for an air leakage test to be performed when a predetermined operation is made at an operating section (3). The CPU uses a pump (21) to force air into a closed space in an arm band (5), said closed space comprising an airbag, an air pipe (10A), and an air pipe (10B), until the closed space reaches a predetermined pressure. Then, the CPU maintains the closed space closed for a predetermined time period and monitors a drop in pressure in the predetermined time period using a pressure sensor (23). When the pressure drops by an amount equal to or more than an allowable value, the CPU determines that there is an air leakage in the closed space comprising the airbag and the air pipes (10A, 10B). Likewise, the CPU causes a closed space comprising the air pipe (10B) to be tested. According to both the test results, the CPU determines whether or not there is an air leakage and whether the portion having the air leakage is in the space comprising the airbag and the air pipes (10A) or in the space comprising the air pipe (10B).
