Problems solved by technology

[0012] However, if the end of the piezoelectric vibrator protrudes from the end surface of the spacer, and the protruding part has a structure suspended in the air, the processing stress generated during the slicing process is likely to cause the problem of cracking of the piezoelectric material.

Abstract

An ultrasonic probe comprises a piezoelectric transducer(1) for transmitting / receiving ultrasonic waves; and a conductive substrate(6) electrically connected to the piezoelectric transducer. The conductive substrate is opposed to a side surface of the piezoelectric transducer. A corner portion(10) formed by the piezoelectric transducer and the conductive substrate is provided with a conductive material for electrically connecting the piezoelectric transducer and the conductive substrate.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from prior Japanese Patent Application No. 2003-46515 filed on February 24, 2003, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an ultrasonic probe for receiving and transmitting ultrasonic waves and a manufacturing method thereof. Background technique [0004] For example, ultrasonic diagnostic devices are used in medical diagnosis and industrial diagnosis, which detect internal lesions and cracks in pipes by emitting ultrasonic waves to diagnostic objects such as human bodies and pipes and receiving reflected waves. This ultrasonic diagnostic device is composed of the ultrasonic diagnostic device itself and an ultrasonic probe for emitting and receiving ultrasonic waves. [0005] Figure 14 with Figure 15 The configuration of an ultrasonic probe of a conventional medical ultrasonic diagno...
