<p>An ultrasonic probe in body cavity dealing with trends toward thinner diameter and multichannel and having enhanced bendability at a bend. The ultrasonic probe comprises an oscillator part (1) for transmitting/receiving an ultrasonic wave arranged in a plurality of channels, and a flexible substrate (2) printed with signal lines connected with respective channels at the oscillator part (1) to supply a transmission signal to the oscillator part (1) and to take out a received signal therefrom, wherein the flexible substrate (2) is constituted by forming at least two channel blocks obtained by dividing the plurality of channels and winding respective channel blocks spirally.</p> |
