PROBLEM TO BE SOLVED: To provide a bendable metal-base circuit board having a good electromagnetic wave shielding property while ensuring heat dissipation and electric insulation, and to provide a manufacturing method thereof and an LED module using it. SOLUTION: In this metal-base circuit board a conductor circuit is provided on metal foil via an insulating layer, and further a cover-lay, a layer having a magnetic loss, or a layer having a dielectric loss is provided. This metal-base circuit board is characterized in that a slit formed by removing at least a part of the cover-lay is formed in a portion wherein the conductor circuit is not provided.
