An integrated circuit board includes a bridging filtering capacitor, a bypass capacitor, a thermistor, and a varistor. The integrated circuit board further includes an electrolytic capacitor set having a plurality of electrolytic capacitors, which are arranged in parallel and adjacent to each other, and a mounting frame for grouping the electrolytic capacitors. The present invention uses the above elements to reduce the vertical height, the horizontal width, and the occupied area. Therefore, the overall dimension of the circuit board can be reduced to make the electronic devices smaller, especially for thin electronic devices such as LCD TVs and screens.
