Antenna device and communication terminal apparatus

A communication terminal apparatus comprising:

• an antenna device;
• and
• a printed wiring board;
• wherein
• the antenna device includes:
• a first insulating base portion including an insulating layer and a spiral antenna pattern including a first end and a second end;
• a second insulating base portion including at least two conductor wires;
• wherein
• the insulating layer and the second insulating base portion are separate and independent layers;
• the insulating layer is configured to insulate the at least two conductor wires from the spiral antenna pattern and is provided between the first end and the second end of the spiral antenna pattern in a plan view;
• the at least two conductor wires include electrode portions electrically and mechanically connected to the first end and the second end, respectively, of the spiral antenna pattern by a conductive material;
• the insulating layer includes a cut or an opening, such that, before the at least two conductor wires are connected to the spiral antenna pattern, at least one of the first end and the second end of the spiral antenna pattern is exposed toward the at least two conductor wires through the cut or the opening;
• and
• the at least two conductive wires are connected to the spiral antenna pattern by the conductive material in the cut or the opening of the insulating layer;
• wherein
• at least one of the conductor wires included in the second insulating base portion is connected to the printed wiring board.
