Abstract

A probe for an ultrasonic diagnostic apparatus is provided which has a supporting plate and a plurality of electro-acoustic transducers arranged in a line on the supporting plate. A thin film with flexibility and watertightness is attached to the electro-acoustic transducers so that the spaces between the adjacent electro-acoustic transducers are hermetically sealed. The result is a reduction in the acoustic coupling between the adjacent transducers.
