Antenna device

An antenna device comprising:

• a core formed from a magnetic material;
• a terminal mounting unit arranged adjacent to one side of the core, the terminal mounting unit having a sidewall member, the sidewall member including opposite sides and a plurality of through holes, each of the plurality of through holes extending from one of the opposite sides to the other of the opposite sides;
• a coil which is arranged on an outer circumference of the core, the coil being a wound conductive wire;
• a coil which is arranged on an outer circumference of the core, the coil being a wound conductive wire;
• a plurality of elongated terminals which are inserted into the plurality of through holes;
• and
• an electronic component provided on the terminal mounting unit,
• wherein the plurality of elongated terminals included a first terminal, and the first terminal is configured with a pin-shaped portion at one end and an outward portion at the other end, and
• when the first terminal is inserted into one of the plurality of through holes, the pin-shaped portion and the outward portion of the first terminal are partially exposed outside of the sidewall member.
