a protection circuit module electrically connected to the core pack and including a switch contact portion; a frame accommodating the core pack and the protection circuit module; and a cover including a recessed portion covering at least a part of the core pack, facing the switch contact portion, and extending toward the protection circuit module. ## Claims ### Claim 1 A battery pack comprising: a core pack comprising a unit cell; a protection circuit module electrically connected to the core pack and comprising a switch contact portion; a frame accommodating the core pack and the protection circuit module, the frame comprising a switch unit corresponding to the switch contact portion; and a cover comprising a recessed portion covering at least a part of the core pack, facing the switch contact portion, and extending toward the protection circuit module, wherein the protection circuit module further comprises a substrate, wherein a first end portion of the substrate is supported by the frame, and a second end portion of the substrate is supported by the recessed portion of the cover. ### Claim 2 (depends on 1) The battery pack of claim 1, wherein the switch unit comprises: a first protrusion extending toward the switch contact portion; and a second protrusion spaced apart from the first protrusion at an interval. ### Claim 3 (depends on 2) The battery pack of claim 2, wherein the second protrusion surrounds the first protrusion. ### Claim 4 (depends on 2) The battery pack of claim 2, wherein a height of the second protrusion is equal to or greater than a height of the first protrusion. ### Claim 5 (depends on 2) The battery pack of claim 2, wherein the protection circuit module comprises a projection corresponding to the second protrusion. ### Claim 6 (depends on 2) The battery pack of claim 2, wherein the second protrusion further comprises an elastic portion at an end portion thereof. ### Claim 7 (depends on 2) The battery pack of claim 2, wherein the first protrusion further comprises an elastic portion at an end portion thereof. ### Claim 8 (depends on 2) The battery pack of claim 2, wherein a groove is formed in the protection circuit module so as to accommodate the second protrusion. ### Claim 9 (depends on 1) The battery pack of claim 1, wherein the cover comprises: a first cover located at a first side of the frame; and a second cover located at a second side of the frame. ### Claim 10 A battery pack comprising: a core pack comprising a unit cell; a protection circuit module electrically connected to the core pack and comprising a switch contact portion; a frame accommodating the core pack and the protection circuit module; and a cover comprising a recessed portion covering at least a part of the core pack, facing the switch contact portion, and extending toward the protection circuit module, wherein the frame comprises a switch unit corresponding to the switch contact portion, wherein the cover further comprises: a first cover located at a first side of the frame; and a second cover located at a second side of the frame, and wherein the recessed portion extending toward the protection circuit module is formed in the first cover so as to correspond to the switch contact portion, and an aperture is formed in the second cover so as to correspond to the switch unit. ### Claim 11 (depends on 1) The battery pack of claim 1, wherein a width of the recessed portion is equal to or greater than a thickness of the substrate. ### Claim 12 (depends on 11) The battery pack of claim 11, wherein an end portion of the recessed portion comprises a first supporting frame and a second supporting frame, and the substrate is located between the first supporting frame and the second supporting frame. ### Claim 13 (depends on 1) The battery pack of claim 1, further comprising an insulating member located between the core pack and the cover. ### Claim 14 (depends on 1) The battery pack of claim 1, wherein the frame comprises high molecular weight compound. ### Claim 15 (depends on 1) The battery pack of claim 1, wherein the cover comprises a metal. ### Claim 16 (depends on 1) The battery pack of claim 1 further comprising a display unit for displaying a state of the core pack. ### Claim 17 (depends on 1) The battery pack of claim 1, wherein the unit cell comprises a polymer-type battery. ### Claim 18 (depends on 1) The battery pack of claim 1, wherein the battery pack is configured to be used in a portable computer.
