Key module and mobile terminal having the same

A mobile terminal comprising:

• a terminal body including a front case, a rear case, and a rear cover coupled to the rear case;
• a key module disposed between the rear cover and the rear case,
• wherein the key module includes:
• a first bracket, comprising:
• a support region supporting a dome switch;
• a side wall part extending along an edge of the support region to form an internal space;
• and
• an adhesive part having one surface adhered to a second bracket, wherein the second bracket is coupled to the first bracket to form the internal space and includes an opening region;
• an adhesive layer formed along edges of the first and second brackets to couple the first and second brackets;
• and
• a sensor bracket allowing a fingerprint sensor unit and a press key unit to be mounted therein, and mounted to be movable in the internal space such that one region of the fingerprint sensor unit is exposed through the opening region,
• wherein:
• one surface of the fingerprint sensor unit is exposed,
• the press key unit is disposed on the other surface of the fingerprint sensor unit,
• the press key unit includes a circuit board and the dome switch is disposed on the circuit board to face the first bracket,
• an outer circumference of the second bracket is formed to be the same as an outer circumference of the adhesive part, and
• the first bracket and the second bracket are integrally fixed by the adhesive layer.
