PROBLEM TO BE SOLVED: To provide solder paste and electric boards capable of suppressing abnormal electrical short-circuiting of adjoining conductive points and a method of manufacturing electric boards. SOLUTION: Adjoining conductive points are assumed to be electrically short-circuited when they are positioned very closely and the application range of solder paste 10 is not constant. However, by gathering magnetic material powder 16 made by coating a magnetic part 16A with an insulating layer 16B among adjoining conductive points by magnetic force, electrical short-circuiting of adjoining conductive points 34 can be suppressed by the insulating layers 16B of the magnetic material powder 16 even when the conductive points 34 are positioned very closely.
