PROBLEM TO BE SOLVED: To settle the problems that, in outdoor farming, crops cultured over a wide range and objects such as Tricholoma matsutake whose growth location cannot be specified, are targeted, so electric stunning work is difficult to perform with conventional ways, efficiently and without omission.SOLUTION: There is provided a device which includes: a receiving part opposed to a discharging electrode in a discharging chamber； an electroshocking part set outside the discharging chamber； and a connecting part 21 passing through the discharging chamber, connected with the receiving part in the discharging chamber and connected with the electroshocking part in the outside. A wheel-shaped electroshocking part is attached to an axle part of the connecting part and the electroshocking part has an insulating disc-like substrate 29 on which plural metal powders 33 are arranged as applying electrodes. The voltage supplied from a high-voltage generator is transmitted/distributed to the metal powders 33 through electrical discharge and gives therefrom electroshock to crops or the like. Thus, the acting range of one electrical discharge is made to be a surface from a point and operation can be efficiently performed without omission.
