Abstract
An ultrasonic coupler provided with an ultrasonic wave propagating member formed of a water-containing polymeric gel and a holder for accommodating said propagating member and fixing it to a probe, which ultrasonic coupler is intended to be interposed between a subject under test and an ultrasonic probe for transmitting and receiving an ultrasonic wave to and from the subject under test and characterized by the fact that said ultrasonic wave propagating member is a water-containing polymeric gel produced by integrally cross-linking an aqueous solution of a water-soluble polymeric compound with said holder inside said holder.
