Claims

[Claims for Utility Model Registration] (1) Strings partially or entirely made of conductive material are strung above the fingerboard of the instrument body, and strings are strung at a plurality of predetermined positions below the string in the stringing direction. An electrical signal is applied to one of the strings and a plurality of fret contact portions that are arranged at intervals of , and can come into contact with the string when the string is pressed. In an electronic stringed instrument in which a contact state is sensed by a fret state sensing means and the musical tone is controlled at a pitch corresponding to a fret operation position sensed by the fret state sensing means, each of the fret contact portions is operated when the string is pressed. a first conductive contact and a second conductive contact that are electrically connected to each other via the string; and an insulator that electrically insulates the first conductive contact and the second conductive contact. An electronic stringed instrument characterized by being composed of a body. (2) The electronic stringed instrument according to claim 1, wherein the first conductive contact and the second conductive contact are provided with a predetermined step difference.
