    摘要： An inductor embedded in a printed wiring board includes a conductor extending in the thickness direction of a printed circuit board and a magnetic body that is in contact with the conductor with no gap therebetween. For example, the magnetic body is composed of ferrite having a cylindrical tubular shape. The conductor is composed of a copper film formed by plating on an inner peripheral surface of the cylindrical tubular ferrite. The inductor is inserted in the thickness direction of the printed wiring board.

    摘要： This invention provides a small package board integrated with power supply capable of supplying a low level of voltage and high level of current to an IC while achieving a low height of its power supply. It becomes hard to saturate an inductor magnetically when the surface of a copper wire is coated with a magnetic layer, and the inductor can accordingly be provided with a sufficient degree of inductance. A multiplicity of inductors can be provided within a confined space by arranging a multiplicity of inductors in parallel, and by fixing them with resin so as to form an inductor array, thereby making it possible to divide a power supply. The number of power supply lines is increased by dividing the power supply so as to reduce the level of current in an individual power supply line, so that a high level of current can be supplied to an IC chip. Further, a distance between a power supply and the IC chip can be decreased by incorporating a power supply module into the package board so as to reduce generation of heat and curb a drop in voltage in the power supply line, thereby making it possible to supply a high level of current to the IC chip.
