In a signal line module and a communication terminal apparatus, a first connection portion connected to a feeding circuit, a second connection portion connected to a radiation element, a first high-frequency line portion, a second high-frequency line portion, and a matching circuit portion defining all of or a portion of a first matching circuit are integrally provided in a multilayer body including a plurality of base material layers. The first connection portion, the first high-frequency line portion, and the matching circuit portion are in a ground zone superposed with a ground conductor, when viewed in plan in a stacking direction of the multilayer body, and the second high-frequency line portion and the second connection portion are in a non-ground zone. The second high-frequency line portion and the second connection portion, together with the radiation element, operate as a radiation portion. |
