摘要:
In order to obtain a high-resolution ultrasound diagnostic image while reducing the back side reflection of a ultrasound irradiated to the side opposite to the ultrasound transmission direction of an ultrasound transmission/reception device, disclosed is an ultrasound probe, wherein a substrate is provided thereon with a cavity, insulation layers having the cavity therebetween, and an upper layer electrode and a lower layer electrode having the cavity and the insulation layers therebetween, so as to form an ultrasound vibration element, the substrate is held by a backing with a low-modulus member therebetween, and a direct voltage and a alternating voltage are applied between the electrodes to vibrate the ultrasound vibration element, and wherein a mechanical impedance by the substrate and the low-modulus member has a substantially equal value as an acoustic impedance of the backing.
