An ultrasound probe (10) connected to an ultrasound diagnostic apparatus (100) transmits an ultrasound beam to a target object. The ultrasound probe (10) includes: a switching unit (16) including a N/2 number (wherein N is a natural number) of channels, each channel switches to a first pole and a second pole first transducer elements (12S) having the N/2 number, connected to the first pole and placed in two-dimension, wherein a placement is defined in x-axis and y-axis and second transducer elements (12T) having the N/2 number, connected to the second pole and placed in two-dimension, wherein the placement is defined in x-axis and y-axis. The placement of a channel number of the first transducer elements (12S) and the placement of the channel number of the second transducer elements (12T) differ in x-axis and y-axis.
