A flexible ultrasonic transducer comprising a flexible metal plate, a piezoelectric ceramics element, a first electrical conductor and an insulation covering a portion of the metal plate. The metal plate comprises a first and a second outer surface opposite each other. The piezoelectric ceramics element is attached to the first outer surface, a first portion of the first outer surface is not covered with the piezoelectric ceramics element, and the first electrical conductor is attached to a first portion of the second outer surface or the first portion of the first outer surface. The first portion of the first outer surface and the first portion of the second outer surface have similar dimensions and positions and the insulation covering covers the first portion of the first outer surface so that the piezoelectric ceramics element is directly dry coupled an object to be inspected by means of the transducer.
