PURPOSE: A circuit board for mounting an LED and a manufacturing method thereof are provided to improve yield by removing defects in a manufacturing process by omitting an additional LED package combination process. CONSTITUTION: A metal board(10) rapidly discharges heat generated by an LED. A circuit pattern(20) is formed by etching a copper layer stacked on the metal board. A terminal pattern(30) is formed on the edge of the board and is upwardly exposed to receive electricity. A resist layer(50) is formed on the remaining circuit pattern except for the terminal pattern and an LED electrode pattern(40). A dam(60) is formed on the resist layer by printing ink with a preset height.
