Abstract
A built-in capacitor type power feed device for an electrical component which solves the problems of the reduction in the noise margin of the power supply system accompanying the lower drive voltages of electrical components and the noise between the power supply and ground accompanying simultaneous switching waveforms, provided with a power supply for supplying power, a printed circuit board including a signal line pattern, a power bar having conductive projections provided in shapes and at positions corresponding to the shapes and positions of electrodes of the electrical component and provided outside of the printed circuit board, a ground bar provided outside of the printed circuit board, and a high dielectric layer provided at a part corresponding to the electrical component between the power bar and the ground bar, power from the power supply being fed to electrodes of the electrical component through the power bar and the ground bar.
