Abstract: To provide an electronic wind instrument capable of accurately detecting the amount of rotation of a transmission member. During an electronic wind instrument performance by a performer, external light (such as light from lighting) may easily shine on the upper surface side of an instrument main body. However, the light-receiving section of an optical sensor faces toward the bottom surface side of the instrument main body therefore external light from the upper surface side of the instrument main body can be prevented from reaching the light-receiving section of the optical sensor. As a result, erroneous detection of the external light by the optical sensor can be suppressed therefore the rotation amount of a transmission member can be accurately detected by the optical sensor.
