Abstract

Various embodiments relating to an electronic device including a key module are disclosed, and according to one embodiment, a portable electronic device comprises: a front glass cover defining the front surface of the electronic device; a rear cover defining the rear surface of the electronic device; a bezel surrounding a space defined by the front cover and the rear cover, the bezel being integrally formed with or separately formed from the rear cover, the bezel including a portion including an opening; a display device built in the space and including a screen area exposed through the front cover; and a plate including a plane parallel to the front cover within the space, wherein the opening penetrates from the outside of the bezel toward the space in a first direction. The electronic device comprises: a key having a size and a shape that can pass through the opening, the key being movably inserted in the opening and including a first surface facing the first direction; a support structure mounted on the plate or a portion of the bezel and including a hole through which the key passes; a dome button mounted on the support structure and arranged to face the first surface of the key and the hole so that the key can be pressed when moving in the first direction; and a waterproof structure including a flexible material. The waterproof structure may comprise: a first portion located between the first surface of the key and the dome button; and a second portion extending from the first portion and inserted between the support structure and the bezel, the second portion sealing a space between the support structure and the bezel so as to waterproof the space. Other various embodiments are also possible.
