Core and coil component

A core comprising:

• a winding core;
• a first flange at a first end portion of the winding core;
• and
• a second flange at a second end portion of the winding core, wherein
• the winding core has a first surface and a second surface on opposite sides, and a first side surface and a second side surface intersecting the first surface and the second surface and on opposite sides,
• the first flange has a first surface and a second surface on opposite sides, a first side surface and a second side surface intersecting the first surface and the second surface and on opposite sides, an inner-side end surface connected to the first end portion of the winding core, and an outer-side end surface on an opposite side from the winding core,
• the inner-side end surface of the first flange has a first inclined surface between the first surface of the winding core and the first surface of the first flange, and a second inclined surface between the first side surface of the winding core and the first side surface of the first flange, and
• a first boundary where the first inclined surface intersects the first surface of the winding core is separated from a second boundary where the second inclined surface intersects the first side surface of the winding core in a direction of an axis of the winding core.
