Claim:
1. A signal line module comprising: a first connection portion connected to a feeding circuit; a second connection portion connected to a radiation element; a first high-frequency line portion, one end of which is connected to the first connection portion; a second high-frequency line portion, one end of which is connected to the second connection portion; and a first matching circuit portion between a second end of the first high-frequency line portion and a second end of the second high-frequency line portion and that defines all of or a portion of a matching circuit configured to perform impedance matching between the first high-frequency line portion and the second high-frequency line portion; wherein the first connection portion, the first high-frequency line portion, the second high-frequency line portion, and the second connection portion are integrally provided in a multilayer body including a plurality of base material layers stacked on top of one another; the first connection portion and the first high-frequency line portion are in a ground zone superposed with a ground conductor, and the second high-frequency line portion and the second connection portion are outside of the ground zone, when viewed in plan in a stacking direction of the multilayer body; the first high-frequency line portion includes: the second high-frequency line portion includes a second signal line not superposed with the ground conductor when viewed in plan in the stacking direction of the multilayer body; all of or a portion of the ground conductor is arranged on a first side of the multilayer body; the second signal line is arranged in a position closer to a second side of the multilayer body than to the first side; and the second high-frequency line portion and the second connection portion, together with the radiation element, define and operate as a radiation portion.
