Provided is an antenna module whereby directivity distortion can be further suppressed. A non-contact type hentenna module (20) is provided with: a substrate (1); a rectangular loop-shaped first conductor (2) that is formed on one surface of the substrate (1); and a rectangular second conductor (6), which is formed, without being short-circuited to the first conductor (2), on the substrate surface on the same side where the first conductor (2) is formed, and which is electrostatically coupled to the first conductor (2) when supplied with power. On a part of one long side of the first conductor (2), a protruding portion (3) is formed, said protruding portion protruding further than other portions of the long side toward at least the inner side of the rectangular loop, a first recessed section (7) and a second recessed section (8) are respectively formed in the protruding portion (3) and a part of the other long side of the first conductor (2), said part facing the protruding portion (3), one end section of the second conductor (6) is inserted to the inner side of the first recessed section (7), and the other end section of the second conductor (6) is inserted to the inner side of the second recessed section (8). |
