This ultrasonic probe comprises 2D array oscillators which are a plurality of oscillators arranged in a two-dimensional array and a 2D array IC which drives the 2D array oscillators, wherein the 2D array IC is configured from a plurality of element channel circuits disposed in a matrix and connected to each of the oscillators on a one-to-one basis. Each of the element channel circuits is configured so as to have a delay circuit provided with N steps of sample-and-hold circuits that include a capacity, write switch, and read switch. |
