Provided are an electronic percussion instrument and a mounting method of a sensor that are capable of accurately detecting a strike on an edge part of a striking surface. An edge frame (17) to which an edge sensor (18) is mounted is connected to the lower surface of a bow portion (12b). Therefore, in the case where the edge part (struck portion (17a)) of the bow portion (12b) is struck, a striking surface frame (12) and the edge frame (17) can be integrally swung with respect to a rod (4). As a result, the relative height between the outer edge of the bow portion (12b) and the struck portion (17a) is less likely to change during performance, making it possible to accurately detect vibration caused by a strike on the edge part of the bow portion (12b) with the edge sensor (18).

Since a bell sensor (14) is mounted to the lower surface of a bell portion (12a) via a bell frame (13), vibration caused by a strike on the bell portion can be transmitted to the bell sensor via the bell frame. Therefore, even if the bell portion is struck in the directly above vicinity of the bell sensor, the output value of the bell sensor can be suppressed from becoming extremely large. Since the bell frame is connected to the lower surface of the bell portion along the circumferential direction, even if the bell portion is struck at a position away from the bell sensor in the circumferential direction, vibration caused by the strike is easily transmitted to the bell sensor via the bell frame. Therefore, the sensitivity distribution of the bell sensor for a strike on the bell portion can be made uniform regardless of differences in striking position.
