A keyboard structure of an electronic keyboard instrument is provided to install a Wippen member and a jack member between a keyboard and a hammer member, thereby enabling a user to feel after-touch impression almost similar to after-touch impression as an essential element of an acoustic piano and minimizing impacts applied to fingers of a player through the keyboard from the hammer. A keyboard structure of an electronic keyboard instrument comprises a keyboard(10), a Wippen member(20), a hammer member(30), a jack member(40), an electric contact(50) and a release member(60). The Wippen member is rotatably installed on a frame(2) and rotates by being pressed by the keyboard when the keyboard is pressed. If force of pressing the keyboard is removed, the Wippen member is elastically rotated to a location for returning the keyboard to an original location. The jack member is rotatably installed in the Wippen member, and upwardly rotates a weight unit(32) by pressing a first operation unit(31) of the hammer member when pressing the keyboard. The jack member has a second operation unit(41) elastically returned to an original location capable of pressing the first operation unit when the pressed state of the first operation unit is released.
