Abstract
Provided is an electronic percussion instrument that can facilitate determination of contact of a detection target conductor with a head. An electronic percussion instrument includes: a tubular body portion with an end surface in an axial direction open; a head that covers the open end surface in the axial direction of the body portion and has a front surface adapted to be hit; and a capacitive sensor that has an electrode disposed on a rear surface side of the head, in which the head includes an electrically isolated conductive head, and no conductor connected to a reference potential point is provided between the front surface of the head and the electrode. In this manner, it is possible to facilitate determination of contact of the detection target conductor with the head.
