PROBLEM TO BE SOLVED: To provide a substrate and a manufacturing method thereof and the like for motor control and the like and also usable with a large current, and integrally configured so as to eliminate the necessity of ferrite core fixing.SOLUTION: A substrate 1 is, for example, a substrate for motor control having a coil 5 which is a choke coil. An electronic component mounting part 9 is formed on the substrate 1, and an internal circuit conductor is exposed to the outside. Other sections than external connecting sections such as the electronic component mounting part 9 are coated with a substrate forming resin to form an injection molded substrate 3. The coil 5 provided on the substrate 1 (the injection molded substrate 3) is for smoothing externally input current. A core section 7 is formed in the coil 5 by a core forming resin such that the core section 7 covers at least a center core 6 of the coil 5.
