ULTRASONIC DEVICE UNIT, PROBE AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic device unit capable of instantaneously supplying a voltage to an ultrasonic element without time delay even when wiring is thinned.SOLUTION: In an ultrasonic device unit DV, a flexible printed circuit board 32 is formed into a loop shape. An ultrasonic device 17 having a first terminal and a second terminal commonly connected to at least one ultrasonic element is mounted onto the flexible printed circuit board 32. First wiring extending from the first terminal toward a first end portion 46 and being connected to an external connection terminal and second wiring extending from the second terminal toward a second end portion 47 and being connected to the external connection terminal via a wiring coupling section of a joint line of the first end portion 46 and the second end portion 47 are formed to the flexible printed circuit board 32.SELECTED DRAWING: Figure 6
