摘要： An ultrasound probe (2) is provided with a first substrate (20) having a silicon substrate (21) and ultrasound transmitting/receiving element (3); an acoustic lens (11) arranged on the upper plane of the first substrate (20); and a dumping layer (41) arranged below the first substrate (20). Furthermore, the ultrasound probe is provided with a second substrate (31) between the lower plane of the first substrate (20) and the upper plane of the dumping layer (41). The second substrate (31) is formed of a material having substantially the same linear expansion coefficient and acoustic impedance as those of the silicon substrate (21) of the first substrate (20). Thus, the ultrasound probe which can prevent the silicon substrate from being damaged due to temperature change, while reducing noise due to reflected wave upon transmission and reception, and has excellent transmission/reception performance and structural reliability is provided.
