PROBLEM TO BE SOLVED: To realize an ultrasonic probe where multiple element making is easy in spite of the use of an inductance coil. SOLUTION: The ultrasonic probe is provided with: an enclosure with its tip closed; an ultrasonic transducer array provided in the inside of the tip part of the enclosure; a signal cable provided on a side opposite to the tip part of the enclosure; a flexible printed board (400) having a circuit pattern for electrically connecting the ultrasonic transducer array with the signal cable in the enclosure; a spiral coil (424) formed as a part of a circuit pattern (402) on the flexible printed board; and a magnetic film (426) provided to the flexible printed board opposing the coil and insulated electrically from it.
