ABSTRACT:
An apparatus which provides a reliable connection of a flexible cable to a transducer unit without damaging the transducer unit. Rounded projections (45) are provided at both ends of the flexible cable (40) when viewed in the direction in which the piezoelectric transducing elements (21) are arrayed, while the rounded projections (45) face a fixing plate (27) onto which the piezoelectric transducing elements (21) are fastened. Each rounded projection has such a height as to prevent the connection terminals of the flexible cable from being inadvertently inserted into the spaces between the adjacent piezoelectric transducing elements of the transducer unit when the flexible cable is located on surface of the transducer unit. At the time of soldering, the connection terminals of the flexible cable (40) are positioned just above the piezoelectric transducing elements (21) of the transducer unit.
