An electronic percussion instrument includes a head, a frame, and an impact sensor, and an air ventilation mechanism which includes a pair of cutouts which are distanced from each other and formed in the periphery of the head. The head is attached to the frame such that the periphery of the frame is externally enclosed with the periphery of the head precluding a pair of cutouts. Additionally, a pair of connecting parts with reduced thickness is linearly elongated across the back of the head in parallel. When the head is struck with a beater, a vibration is caused to occur in the head and detected by the impact sensor to produce an electric signal which is used to generate an electronic musical sound, wherein the air ventilation mechanism releases air from the back of the head so as to reliably secure noiselessness while reducing noise.

1. An electronic percussion instrument comprising: a frame having a head-attaching portion;a head, which is made of an elastic material with a higher flexibility than the frame, which includes a main strike area which is disposed on a surface and mainly subjected to a striking operation, and whose periphery is directly fixed to the head-attaching portion of the frame or whose periphery is fixed to the head-attaching portion of the frame via a joint member; andan impact sensor which converts a vibration occurring on the main strike area subjected to a striking operation into an electric signal,wherein an opening which allows air to transmit there through at the striking operation is formed in a portion of the head circumventing the main strike area such that the main strike area is opening-free. 2. The electronic percussion instrument according to claim 1, wherein the opening includes at least a pair of a first opening and a second opening, the first opening and the second opening being spaced apart from each other by a portion of the head circumventing the main strike area that does not include an opening. 3. The electronic percussion instrument according claim 2, further comprising a cover which is used to cover the periphery of the head, wherein a through-hole is formed at a position of the cover corresponding to the opening. 4. The electronic percussion instrument according to claim 2, wherein the impact sensor is disposed close to the main strike area of the head via a cushion material. 5. The electronic percussion instrument according to claim 1, wherein the opening is a cutout, and wherein the head is attached to the frame such that the periphery of the frame is externally enclosed with the periphery of the head except at the cutout. 6. The electronic percussion instrument according to claim 5, wherein a thinned portion which is elongated in a horizontal direction is formed in the head, and wherein the cutout is formed at each of opposite ends of the thinned portion in the periphery of the head. 7. The electronic percussion instrument according claim 6, further comprising a cover which is used to cover the periphery of the head, wherein a through-hole is formed at a position of the cover corresponding to the opening. 8. The electronic percussion instrument according to claim 6, wherein the impact sensor is disposed close to the main strike area of the head via a cushion material. 9. The electronic percussion instrument according to claim 5, wherein an upper connecting part and a lower connecting part which are linearly elongated in a horizontal direction is formed in the head, wherein an upper area above a main area including the main strike area of the head is connected to the main area via the upper connecting part while a lower area below the main area is connected to the main area via the lower connecting part, wherein the upper connecting part and the lower connecting part are reduced to be thinner in thickness than the upper area and the lower area, and wherein the cutout is formed in the main area within the periphery of the head. 10. The electronic percussion instrument according claim 9, further comprising a cover which is used to cover the periphery of the head, wherein a through-hole is formed at a position of the cover corresponding to the opening. 11. The electronic percussion instrument according to claim 7, wherein the impact sensor is disposed close to the main strike area of the head via a cushion material. 12. The electronic percussion instrument according claim 5, further comprising a cover which is used to cover the periphery of the head, wherein a through-hole is formed at a position of the cover corresponding to the opening. 13. The electronic percussion instrument according to claim 5, wherein the impact sensor is disposed close to the main strike area of the head via a cushion material. 14. The electronic percussion instrument according to claim 1, further comprising a cover which is used to cover the periphery of the head, wherein a through-hole is formed at a position of the cover corresponding to the opening. 15.
