To provide a light-emitting diode illumination module which is easy to assemble, excellent in heat sink property, reliable, small, high usability and high illuminance.

The module is provided with a flexible wiring board, obtained by forming a circuit wiring 3 on a flexible board 2a, forming a flexible board 2b on it via an adhesive 8, and forming a flexible reflecting layer 7a reflecting light from the dice 1 of a light-emitting diode on it. A heat spreader 9, mounting the dice 1 of the light-emitting diode, is provided through the flexible wiring board. The dice 1 of the light-emitting diode is connected with the circuit wiring 3, provided on the flexible board 2a through a metal wire 5. In the flexible wiring board like this, an area provided with the heat spreader 9 is a part difficult to deform, and the other area is a part which is easy to deform.
