15. An electronic device, comprising:
a housing including a touch switch portion; and
a touch sensing device configured to sense either one or both of a force touch and a contact touch, in response to a touch being applied to the touch switch portion,
wherein the touch sensing device includes:
a force sensing unit including a sensing coil;
a metal portion, at least a portion of the metal portion being in contact with the force sensing unit, and the touch sensing device being configured such that a region of the metal portion overlapping the sensing coil changes in response to the touch being applied to the touch switch portion; and
a bracket disposed to be spaced apart from the housing, and supporting the force sensing unit and the metal portion such that the metal portion is disposed between the housing and the bracket.
