Coil component (10), comprising: a cylindrical core (10C) with a columnar winding core section (11), a first
flange section (20) connected to a first end of the winding core section (11) in a direction along a central axis (C) of the winding core section (11), and a second
flange section (30) connected to a second end of the winding core section (11) opposite the first end; a first
metal connection (41) attached to the first
flange section (20); and a wire (51) which is wound around the winding core section (11) and has a first connecting end which is attached to the first
metal terminal (41), where an axis orthogonal to the central axis (C) is defined as a first axis (X) and one of the directions along the first axis (X) is defined as a first
positive direction (X1), wherein the first flange section (20) projects outwards in the first
positive direction (X1) with respect to the winding core section (11), wherein the first
metal connection (41) has: a bond section (410) attached to the first flange section (20), with an
adhesive (60) arranged between them; a mounting section (430) located closest to one side of the first
positive direction (X1) in the first metal terminal (41); and a
coupling section connecting the bonding section (410) and the
assembly section (430), and wherein the
assembly section (430) is spaced from the cylinder core (10C) on the side of the first positive direction (X1), wherein the first flange section (20) has an upper surface (21A) facing the side of the first positive direction (X1) and a projecting section (22) extending from the upper surface (21A) in the direction of the side of the first positive direction (X1), wherein, where a direction opposite to the first positive direction (X1) is defined as a first negative direction (X2), and an axis orthogonal to both the central axis (C) and the first axis (X) is defined as a second axis (Y), the projecting section (22) has an upper end face (22A) facing the mounting section (430) from one side of the first negative direction (X2), and a side face (22B) connecting the upper end face (22A) of the projecting section (22) and the upper face (21A) of the first flange section (20) and intersecting the second axis (Y), and wherein the first metal connection (41) has an extension section (440) extending from the mounting section (430) and in contact with the side surface (22B), wherein the extension section (440), when viewed in the direction along the central axis (C), has a section extending towards a center of the protruding section (22) in the first negative direction (X2).
