Abstract
Abstract A transmission transducer (9; 34) produces an ultrasonic wave and applies it to the blood vessel (12), and a reception transducer (9; 52) provided at a puncturing needle (1) receives the ultrasonic wave reflected by the blood vessel (12) through the puncturing needle (1). When the reception transducer (9; 52) receives the reflected ultrasonic wave, the puncturing needle (1) faces the blood vessel (12)
