Abstract
An ultrasonic probe is characterized in that a piezoelectric memberformed of solution-based single-crystal containing at least plumbum titanate is sandwiched between resin layersandhaving smaller acoustic impedance than the piezoelectric member and having conductivity, so processing errors are prevented from occurring during cutting and the resin layers can be used as acoustic layers or electrodes.
