PROBLEM TO BE SOLVED: To obtain a semiconductor circuit board, having an electromagnetic noise suppressor formed with an insulation film interposed which can effectively absorb jamming electromagnetic waves, ranging from MHz bands to GHz bands and reveal an electromagnetic wave absorption effect, when it is divided into individual semiconductor elements. SOLUTION: The semiconductor circuit board has an electromagnetic noise suppressor 4 formed from a soft magnetic film formed through an insulation film at a specified position on an IC circuit pattern 11 covered with an insulation film 9, and the noise suppressor 4 is formed over the entire surface of the IC circuit pattern via the insulation film 9 and processed into a fine pattern, having at least a size which is not greater than minimum widths of power lines 2 and ground lines 3 of the IC circuit pattern.
