There is provided an ultrasound probe including a capacitive transducer for reducing multiple reflections while maintaining a pulse characteristic with which a high-quality image can be obtained, and is also provided an ultrasound imaging apparatus using the ultrasound probe. The ultrasound probe including the capacitive transducer is configured so as to satisfy the condition 6.5/f c <；±d, where ± [dB/mm/MHz] denotes the absorption coefficient of an acoustic lens, d [mm] denotes the maximum thickness of the acoustic lens, and f c [MHz] denotes the center frequency of the capacitive transducer, and satisfy the condition L<；1/((3Àf c ) 2 ×C), where L [H] denotes an inductance value per channel of the capacitive transducer, C [pF] denotes a capacitance per channel of the capacitive transducer, and f c [MHz] denotes the center frequency of the capacitive transducer.
