1. An antenna device comprising:
a case;
an antenna body accommodated in the case and including:
a bobbin that extends in a first direction and includes a pair of side walls that have inner surfaces that face each other in a second direction that intersects the first direction,
a winding wound around the bobbin to collectively surround the pair of side walls, the winding having an axial direction that is parallel to the first direction, and
a core held by the pair of side walls in such a manner as to be located between the inner surfaces of the pair of side walls in an inner space defined by the winding,
wherein at least one of the inner surfaces of the pair of side walls includes an inclined surface, and
wherein the inclined surface overlaps the core in a third direction so as to be positioned closer to the core than the winding, with the third direction intersecting both the first direction and the second direction.
