摘要： PURPOSE:To improve reliability by surely connecting wiring, which electrically connects a power supply side and a contact level side, without being degraded by the friction of a holder, and turning this wiring to low resistance so as to be hardly corroded by contact medium liquid at the ultrasonic probe. CONSTITUTION:First of all, a spherical face 2 of a main body 1 of an acoustic lens having silicon as a material and through holes 3, 4 are formed from a contact level side by etching. Thus, the through holes 3, 4 are enlarged on the contact level side and reduced on the power supply side. Next, a lower electrode 5, piezoelectric film 6 and upper electrode 7 are formed by vapor- depositing a conductor onto the spherical face 2 of the acoustic lens 1 and at such a time, however, wirings 20, 21 to electrically connect the power supply side and contact level side of the main body 1 of the acoustic lens are simultaneously formed as well by utilizing the shapes of the through holes 3, 4.
