摘要： An ultrasound transducer of the present invention includes elements each provided with an electromechanical conversion element that converts an electric signal inputted between a first electrode and a second electrode into vibration, an array section made up of n elements in a row direction and m elements in a column direction (nm) arranged in a matrix form, and an array forming section that switches between a one-dimensional array state column-wise made up of m element groups formed by electrically connecting the first electrode terminals neighboring in the row direction out of the first electrode terminals in the element groups arranged on the same column and a one-dimensional array state row-wise made up of n element groups formed by electrically connecting the first electrode terminals neighboring in the column direction out of the first electrode terminals in the element groups arranged on the same row in the array section.
