Electronic wind instrument and manufacturing method thereof

An electronic wind instrument, comprising:

• an instrument main body;
• a blow port which is attached to one end of the instrument main body and has a cavity therein;
• a reed which is attached to the blow port and is configured to be displaceable toward the cavity when bitten by a performer;
• a transmission member that is configured to be rotatable around a predetermined axis with displacement of the reed when one end of the transmission member is brought into contact with the reed;
• a detection unit which is disposed on the other end side of the transmission member;
• and
• a sensor which is disposed to face the detection unit and measures a distance between the sensor and the detection unit,
• wherein when the reed is displaced due to being bitten by the performer, the detection unit of the transmission member rotates away from the sensor;
• wherein the sensor is an optical sensor having an output characteristic in which when a distance to the transmission member is a predetermined value, an output voltage from the sensor reaches a peak, and
• wherein in an initial state before the reed is displaced, a distance between the detection unit and the sensor which face each other is set to be larger than the predetermined value.
