Abstract
A laminated electronic component has a structure in which an micro-strip line (MSL) is formed in a first dielectric layer, and a first ground layer and an adjustment pattern layer are formed on the top surface and the base surface of the first dielectric layer, respectively. A second dielectric layer is formed between the adjustment pattern layer and a second ground layer, comb teeth-shaped parallel electrodes having an area larger than that of the MSL is formed at a position opposed to the MSL in the adjustment pattern layer. A slit is formed not to be opposed to the MSL in the second ground layer and to be opposed to the connection points of the parallel electrodes. By emitting a laser beam from the direction of the second ground layer through the slit and the second dielectric layer, and separating the connection points of the parallel electrodes, the capacitance between the MSL and the ground can be adjusted in steps, which increases the resonant frequency of the MSL.
