PROBLEM TO BE SOLVED: To provide a flexible printed circuit board capable of enlarging intervals of mutually adjacent conductor parts while inhibiting enlargement of the width in an elevation direction of an ultrasonic probe.SOLUTION: A flexible printed circuit board 50 includes a plurality of conductor parts 52 that are electrically connected to a plurality of ultrasonic transducers disposed in an azimuth direction in a housing of an ultrasonic probe, and are formed at required intervals X1. The flexible printed circuit board 50 is provided in the housing so as to be pulled out in the azimuth direction, and includes a narrow width portion 55 that has a minimum width or less in the elevation direction in an inner space at the end of the housing in a contact surface side with a subject, and wide width portions 56 that are formed on both sides of the narrow width portion 55 and have the width larger than that of the narrow width portion 55. 【課題】超音波プローブのエレベーション方向における幅を抑制しつつ、互いに隣り合う前記導体部の間隔を広くすることができるフレキシブルプリント基板を提供する。【解決手段】フレキシブルプリント基板５０には、超音波プローブの筐体内においてアジマス方向に配列された複数の超音波振動子と電気的に接続される複数の導体部５２が所要の間隔Ｘ１で形成されている。フレキシブルプリント基板５０は、アジマス方向に引き出されるように前記筐体内に設けられており、被検体との当接面側の前記筐体の端部における内部空間のエレベーション方向における最小幅以下の幅を有する幅狭部５５と、幅狭部５５の両側に形成され幅狭部５５よりも大きな幅で形成された幅広部５６とを有する。【選択図】図６
