PROBLEM TO BE SOLVED: To provide a portable terminal which maintains the elasticity of a key sheet and maintains good acoustic properties of an acoustic component without impairing key click feeling even when an external pressure is applied to a housing.SOLUTION: A portable terminal 10 comprises: a shelf part 13 provided in an interior part 12 of a housing 11; a circuit board 14 fixed to a surface 13A of the shelf part 13; pressing pieces 18 which are provided on a rear surface 17A of a key sheet 17 protruding therefrom and may contact with a contact part 15; a waterproof film 25 provided on the rear surface 17A of the key sheet 17; an elastic member 26 disposed with an annular second adhesion part 28 and an annular third adhesion part 29 interposed therebetween; an acoustic component 32 fixed to a rear surface 13B of the shelf part 13; and protruding parts 22 provided on the rear surface 17A of the key sheet 17 and protruding toward the shelf part 13. When the elastic member 26 is compressed a predetermined amount along a thickness direction, the protruding parts 22 come in contact with the surface 13A of the shelf part 13. |
