1. In a piezoelectric shock wave generator for use in medical equipment and including a plurality of piezoelectric elements being electrically interconnected to operate in parallel and mounted on a common carrier, there being a coupler medium for coupling shock waves as generated by these piezoelectric elements into the body of a living being, wherein the improvement comprises an electrical insulation between the piezoelectric elements being in a fluid state, in that each of said piezoelectric elements is surrounded by the fluid insulation, and in any direction towards any other of the piezoelectric elements, said insulation having a breakthrough strength in excess of about 5 KV/mm, being larger than the breakthrough strength of air.
