Ultrasonic probe

A manufacturing method for an ultrasonic probe including the steps of forming a plurality of unit fixing plates. Laminating each unit fixing plates to one another to form a fixing base and inserting lead wires into grooves formed in the fixing base. Partially cutting away and smoothing both principal surfaces of the fixing base to expose lead wires. Fixing a piezoelectric plate to one principal surface of the fixing base and cutting out between the lead wires in a one dimension direction and a two dimension direction, to divide up said piezoelectric plate and the fixing base into a plurality of piezoelectric elements.

Ultrasonic probe and manufacturing process thereof

The invention relates to an ultrasonic probe in which the array accuracy of lead wires, and heat resistance when connecting to a connector are enhanced, and a manufacturing method therefor. The ultrasonic probe of the invention is one in which a plurality of piezoelectric elements are arrayed in a two-dimensional direction on a fixing base, and lead wires from the lower surface of each of the piezoelectric elements are inserted through the fixing base, and the electrically connected lead wires are led out, and the fixing base has an opening portion in an array direction of the piezoelectric elements, and comprises unit fixing plates laminated in the array direction, and grooves through which the lead wires are inserted, are formed on one principal surface of the unit fixing plates, and damper material is filled into the opening portion. The invention is also for a manufacturing method for the ultrasonic probe.
