The middle plate can include a first portion disposed between the front plate and the side members, when viewed from the outside of the housing. The first portion can include: a first surface supporting a portion of the front plate and facing the first direction; a second surface exposed to the outside of the housing; a third surface facing a third direction that is different from the first direction and the second direction, and facing the side surface of the front plate; and a protruding part protruding in the third direction on the third surface. ## Claims ### Claim 1 An electronic device comprising: a housing including a front plate oriented in a first direction, a rear plate oriented in a second direction opposite the first direction, and a side member surrounding an internal space between the front plate and the rear plate; a display visible through at least a portion of the front plate; and a mid-plate located between the front plate and the rear plate, wherein, the mid-plate includes a first portion disposed between the front plate and the side member when viewed from an outside of the housing, and the first portion includes: a first surface supporting a portion of the front plate and oriented in the first direction; a second surface exposed to the outside of the housing; a third surface oriented in a third direction different from the first direction and the second direction, and facing a side face of the front plate; and a protrusion protruding in the third direction on the third surface. ### Claim 2 (depends on 1) The electronic device of claim 1, wherein the protrusion is located between a first point at which the first surface meets the third surface and a second point at which the second surface meets the third surface when viewed in a cross section of the first portion. ### Claim 3 (depends on 2) The electronic device of claim 2, wherein the protrusion is disposed at substantially a same distance from the first point and the second point. ### Claim 4 (depends on 1) The electronic device of claim 1, wherein the third direction is substantially perpendicular to the first direction. ### Claim 5 (depends on 1) The electronic device of claim 1, wherein the first portion includes: a first region including a region exposed to an outside of the electronic device; and a second region extending from the first region and supporting the display. ### Claim 6 (depends on 5) The electronic device of claim 5, wherein the first region includes: a first section extending from an end of the second region; a second section extending from the first section in the first direction; and a third section extending from the second section in the first direction and including a curved shape on a face oriented in the first direction. ### Claim 7 (depends on 6) The electronic device of claim 6, wherein the first region is inclined or curved so as to gradually decrease in size from the first section toward the second section and the third section. ### Claim 8 (depends on 6) The electronic device of claim 6, wherein the third surface includes: a (3-1)th face disposed in the first section and having a length of 40% to 60% of the third surface, a (3-2)th face disposed in the second section and extending from the (3-1)th face; and a (3-3)th face disposed in the third section and extending from the (3-2)th face so as to form a curved face, and the protrusion is disposed to protrude from a portion of the (3-2)th face toward an inside of the electronic device. ### Claim 9 (depends on 8) The electronic device of claim 8, wherein the protrusion is disposed so as not to be exposed to a field of view when viewed from the outside of the electronic device. ### Claim 10 (depends on 8) The electronic device of claim 8, wherein a height of the second section is smaller than a height of the first section, a height of the third section is smaller than a height of the second section, and the height of the third section has a length of 0.1 mm to 0.4 mm. ### Claim 11 (depends on 2) The electronic device of claim 2, wherein the third surface forms a predetermined slope with respect to a first direction perpendicular to the first surface, and the predetermined slope ranges from 1 degree to 4 degrees. ### Claim 12 (depends on 2) The electronic device of claim 2, wherein the first portion and the protrusion are formed of a same injection-molded material, and the injection-molded material is at least one of polystyrene (PS), acrylonitile butadiene styrene (ABS), polyphthalamide (PPA), polyamide (PA), polyphenylene sulfide (PPS), modified polyphenylene oxide (MPPO), acrylic, or polycarbonate (PC). ### Claim 13 (depends on 2) The electronic device of claim 2, wherein the mid-plate is manufactured through injection molding, and gas generated during the injection molding is discharged from the (3-2)th surface of the second section. ### Claim 14 (depends on 2) The electronic device of claim 2, wherein a plurality of first portions, in each of the protrusion is formed, are disposed along an edge region of the electronic device. ### Claim 15 An electronic device comprising: a display; and a housing including a first region including a portion exposed to an outside of the electronic device and a second region supporting at least a portion of the display, wherein the first region includes: a first section extending from an end of the second region; a second section extending from the first section in a first direction and including at least one protrusion protruding into the electronic device; and a third section extending from the second section in the first direction and including a curved shape on a face oriented in the first direction, and the protrusion is disposed not to be exposed to an outside of the electronic device.
