Title:
ULTRASONIC TRANSDUCER AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2023/203879
Kind Code:
A1
Abstract:
A flexible printed circuit board (140) includes a first surface section (141), a second surface section (142) and a third surface section (143). The first surface section (141) has a first electrode (145) electrically connected to a piezoelectric element (120), and extends so as to contact a first main surface (121) of the piezoelectric element (120). The second surface section (142) curves and stands upright from the edge of the first surface section (141) near a lateral wall section (112) of a case (110), and extends along said lateral wall section (112). The third surface section (143) has a second electrode (146) electrically connected to a first end section (131) of a terminal member (130), curves in an S-shape from the upper end of the second surface section (142), and faces the first surface section (141) with an interval interposed therebetween. The first surface section (141) and at least the section of the second surface section (142) which is near the first surface section (141) are embedded in a first filler material (150).
