PROBLEM TO BE SOLVED: To provide a metal printed circuit board, where each individual piece is bent and an electronic component mounted to the individual piece is not subjected to bending stress even if bending and cutting at a groove for division formed on a substrate sheet are performed for separation into pieces becoming the metal printed circuit board. SOLUTION: In the metal printed circuit board 2, a conductive pattern is formed, and pieces 11 are separated from a substrate sheet 1 in which a plurality of pieces 11 for mounting electronic components 21 are formed. The groove 3 for division is formed at a connection portion 10a between respective individual pieces 11 on the substrate sheet 1 and a portion 10 other than the individual pieces. A through hole 4 for allowing the individual pieces 11 to pass through is formed between the groove 3 for division of the individual pieces 11 and the electronic component 21 mounted to the individual pieces 11.
