A mobile device is provided to reduce the thickness of parts and freely execute individual replacement by separably installing a housing at a main substrate of the mobile terminal. A mobile device comprises an operation part(110), a magnet(114), an elastic body(120), a substrate(140), a magnetic sensor(144), a housing(130), and the second stepped part. The operation part(110) has a contact part a user touches. The magnet(114) is coupled to the operation part(110). The elastic body(120), combined with the lower surface of the operation part(110), applies elastic force to the operation part(110). The upper surface of the substrate(140) confronts the lower surface of the operation part(110). On the upper surface of the substrate(140), a plurality of coupling slots are formed. The magnetic sensor(144), combined with the lower surface of the substrate(140), detects magnetic force from the magnet(114). The housing(130), which covers a portion of the operation part(110), has an opening part so that the contact part can be exposed to the external. Also the housing(130) has plural coupling bosses which are inserted into the coupling slots. At the outer circumference of the housing(130), the first stepped part(134), which engages with the second stepped part, is formed.
