An electronic device comprising: first operation means including a touch operation surface on which a touch operation and a slide operation are performed; a touch detection surface placed under the touch operation surface and configured to detect the touch operation; and a gripping portion configured to be held by a user, wherein the touch detection surface is divided into at least two detection surfaces (302a, 302b, 302c) including a first detection surface to an N-th detection surface in order from a side distant from the gripping portion in a direction of the slide operation, wherein the gripping portion is provided closest to the N-th detection surface among the at least two touch detection surfaces (302a, 30sb, 302c) in the direction of the slide operation, wherein the touch operation surface includes a first operation surface, and a second operation surface extending around the outer edge of the first operation surface, wherein the first and second operation surfaces (303a, 303b) are different from each other in at least one of amount of protrusion, texture, and color, wherein the second operation surface overlaps the first detection surface provided on the outer edge of the first operation surface on the side distant from the gripping portion wherein the touch operation surface is arranged to be operable by the slide operation with a thumb of a gripping hand of a user who grips the gripping portion, and wherein the first operation surface and the first detection surface overlap each other in an area of a first touch detection region which is greater than an area of a second touch detection region (302a2) where the second operation surface and the first detection surface overlap each other. first operation means including a touch operation surface on which a touch operation and a slide operation are performed; a touch detection surface placed under the touch operation surface and configured to detect the touch operation; and a gripping portion configured to be held by a user, wherein the touch detection surface is divided into at least two detection surfaces (302a, 302b, 302c) including a first detection surface to an N-th detection surface in order from a side distant from the gripping portion in a direction of the slide operation, wherein the gripping portion is provided closest to the N-th detection surface among the at least two touch detection surfaces (302a, 30sb, 302c) in the direction of the slide operation, wherein the touch operation surface includes a first operation surface, and a second operation surface extending around the outer edge of the first operation surface, wherein the first and second operation surfaces (303a, 303b) are different from each other in at least one of amount of protrusion, texture, and color, wherein the second operation surface overlaps the first detection surface provided on the outer edge of the first operation surface on the side distant from the gripping portion wherein the touch operation surface is arranged to be operable by the slide operation with a thumb of a gripping hand of a user who grips the gripping portion, and wherein the first operation surface and the first detection surface overlap each other in an area of a first touch detection region which is greater than an area of a second touch detection region (302a2) where the second operation surface and the first detection surface overlap each other.
