Abstract: A control device of an electrostimulator is used in the electrostimulator including an electrode, an angular velocity sensor, and a notifier. The control device includes a controller that controls electrostimulation which is output from the electrode and that counts the number of times of movements as the number of times of the reciprocating movements of the target site; and a storage that stores preset information. The storage stores a first threshold value and a second threshold value. The controller causes the notifier to display movement information including the number of times of the movements, based on a state in which an angular velocity reaches the second threshold value after reaching the first threshold value.
