Provided is a board-cable connection structure that is capable of reducing size and height of connecting parts of cables and a circuit board without impairing reliability of electrical connection of cables and the circuit board. A board-cable connection structure comprises a circuit board 2, a multiplicity of cables 3, a relay connector 6 having FPC for electrically relaying and connecting the multiplicity of cables 3 to the circuit board 2, and a protective cover 7 that covers the relay connector 6 and prevents the relay connector 6 from moving in the direction separating away from the circuit board 2.
