23. An antenna comprising;
-
a base that has a first surface and a second surface that is a back in relation to the first surface; a first surface electrically conductive portion that is formed on the first surface of the base and, two end of which are a first surface first end portion and a first surface second end portion; a second surface electrically conductive portion that is formed on the second surface of the base and, two end of which are a second surface first end portion and a second surface second end portion, wherein the second surface electrically conductive portion coincides with the first surface electrically conductive portion when viewed transparently from the first surface side in a direction of the second surface; a first through hole conducting portion that penetrates between the first surface and the second surface allows the first surface first end portion and the second surface first end portion to be electrically connected to each other; and a second through hole conducting portion that penetrates between the first surface and the second surface allows the first surface second end portion and the second surface second end portion to be electrically connected to each other.

24. An antenna comprising:
-
a plurality of electrically conductive portions that are layered with a base interposed between the adjacent electrically conductive portions, each electrically conductive portion having a first end portion and a second end portion; a through hole conducting portion that penetrates the base and allows the first end portions of the electrically conductive portions to be electrically connected to each other; and a through bole conducting portion that penetrates the base and allows the second end portions of the electrically conductive portions to be electrically connected to each other, wherein all of the plurality of electrically conductive portions coincide with each other when viewed transparently along a layering direction.
