PURPOSE:To obtain a miniaturized chip directional coupler. CONSTITUTION:Strip line electrode boards 3, 4 on each major side of which 1/4 wavelength strip line electrode parts 3f, 4f are formed meanderingly are laminated while strip line electrodes 3b, 4b are coupled electromagnetically and two ground electrode boards 2, 5 with ground electrodes 2b, 5b formed thereon are laminated while the two strip line electrode boards 3, 4 are inserted, plural outer electrodes are formed to the flank of the laminator and each end of the strip line electrodes 3b, 4b and the ground electrodes 2b, 5b are connected electrically to each outer electrode. |
