a board on which an electrode is formed, the core wire being electrically connected to the electrode at an end face of the cable; and a compressing member attached to an outer periphery of the cable and radially compressing a part in a longitudinal direction of the cable. ## Claims ### Claim 1 A cable connection structure comprising: a cable including a core wire and an external covering layer covering the core wire; a board on which an electrode is formed, the core wire being electrically connected to the electrode at an end face of the cable; and a swaging member attached at a longitudinal position to at least a part of an outer periphery of the cable and radially compressing at least a portion of the cable at the longitudinal position. ### Claim 2 (depends on 1) The cable connection structure according to claim 1, wherein an outer diameter of the swaging member at the longitudinal position is equal to a diameter of the cable at a region without the swaging member attached. ### Claim 3 (depends on 1) The cable connection structure according to claim 1, wherein the swaging member is attached to a groove formed at the longitudinal position in the external covering layer. ### Claim 4 (depends on 1) The cable connection structure according to claim 1, wherein the longitudinal position is adjacent to an end face portion of the cable on the side of the board. ### Claim 5 (depends on 4) The cable connection structure according to claim 4, wherein the end face portion is formed by cutting the cable a predetermined distance from the swaging member. ### Claim 6 (depends on 5) The cable connection structure according to claim 5, wherein the end face portion is further formed by substantially removing the predetermined distance from the cable. ### Claim 7 (depends on 1) The cable connection structure according to claim 1, wherein the cable is a coaxial cable including: an internal insulating layer formed around the core wire; and an external conductive layer formed around the internal insulating layer and inside the external covering layer. ### Claim 8 (depends on 7) The cable connection structure according to claim 7, wherein the swaging member is attached to a region from which the external covering layer has been removed. ### Claim 9 (depends on 8) The cable connection structure according to claim 8, wherein the swaging member is formed of a conductive material. ### Claim 10 (depends on 9) The cable connection structure according to claim 9, wherein the swaging member includes a coating formed of an insulating material on an outer peripheral surface of the swaging member. ### Claim 11 (depends on 8) The cable connection structure according to claim 8, wherein the swaging member is formed of an insulating material. ### Claim 12 (depends on 1) An endoscope apparatus comprising: the cable connection structure according to claim 1; and an imaging element connected to the electrode formed on the board. ### Claim 13 (depends on 12) The endoscope apparatus according to claim 12, further comprising: a distal-end hard portion housing at least the imaging element, the board, and the swaging member; and a flexible housing portion housing the cable protruding from the distal-end hard portion. ### Claim 14 (depends on 1) The cable connection structure according to claim 1, wherein the end face portion of the cable includes a polished surface. ### Claim 15 (depends on 1) The cable connection structure according to claim 1, wherein an inner diameter of the swaging member at the longitudinal position is smaller than a diameter of the cable at a region without the swaging member attached. ### Claim 16 A cable connection structure comprising: a plurality of cables aligned to be in contact with each other at a part of an outer periphery thereof, each cable including a core wire and an external covering layer covering the core wire; a board on which a plurality of electrodes is formed, the core wires being electrically connected to the electrodes at end faces of the plurality of cables; and a swaging member attached at a longitudinal position to at least a part of outer peripheries of the plurality of cables and radially compressing at least a portion of the plurality of cables at the longitudinal position. ### Claim 17 (depends on 16) The cable connection structure according to claim 16, wherein the swaging member is attached along the outer peripheries of the plurality of cables. ### Claim 18 A cable connection structure comprising: a cable including at least a core wire and an external covering layer covering the core wire; a board on which an electrode is formed, the core wire being electrically connected to the electrode at an end face of the cable; and a compressing member attached to an outer periphery of the cable and radially compressing the external covering and at least the core wire of the cable. ### Claim 19 (depends on 18) The cable connection structure according to claim 18, wherein the compressing member is formed of a conductive material.
