Abstract
First and second electrodes are formed on a pair of opposite surfaces of a polyimide film. The first and second electrodes respectively have a large number of small holes which oppose each other through the polyimide film. An excimer laser beam is radiated on one of the first and second electrodes. A portion of the excimer laser beam radiated on the electrodes is reflected by the electrode surfaces. The remaining portion of the laser beam radiated inside the holes of the electrodes disconnects the chemical bond of the polyimide without generating heat. As a result, holes each having a sectional shape defined by a corresponding hole fomed in the electrodes are formed in the solid insulating body.
