In a handheld piezoelectric acupuncture stimulator with a pen-like, substantially electrically insulating exterior casing ( 1 ), at one end of which an actuator button ( 5 ) is mounted, while the other end is provided with a contact pin ( 9 ), which is connected with a first electrode of a piezoelectric converter, which by means of a spring-loaded impact hammer actuated by the actuator button ( 5 ) may be mechanically operated for generation of a high voltage electric pain relieving pulse with a low energy content, the piezoelectric converter with associated electrodes and said impact hammer with associated spring system are mounted in a common electrically insulating interior casing ( 8 ) designed for form-fit mounting in the exterior casing ( 1 ), whereby the electric connection between the second electrode of the piezoelectric converter and a contact ring ( 7 ) on the exterior casing comprises a leaf spring contact ( 10 ), which projects through the interior casing ( 8 ) and extends between said interior casing and the exterior casing ( 1 ).
