A transmission line type component (1, 1') having an arrangement in which a coaxial line having a very low characteristic impedance is constructed by coaxially arranging a cylindrical external conductor which is formed from a conductive material and has a larger diameter than that of an internal conductor so as to cover, via a high-k insulating member, the surface of the internal conductor which is formed from a conductive material is inserted in series between a power supply line (8) and ground line (9), which are connected to a DC power supply on a printed circuit board, and the power supply port of an LSI (6). With this arrangement, most of a high-frequency power supply current generated from the LSI (6) is reflected by the power supply port of the LSI (6). Part of the high-frequency power supply current which enters the component (1, 1') is consumed by the dielectric loss and does not reach the external power supply line (8). <IMAGE> |
