Abstract: An inductor component includes an element body having a magnetic material, and a coil that is disposed inside the element body. The coil includes a coil wire that is spirally wound along an axis with a first end of the coil wire at a positive side of the axis and a second end of the coil wire at a negative side of the axis. At least one of a first end surface of the first end of the coil wire and a second end surface of the second end of the coil wire includes a recess, and a portion of the element body is located inside the recess.

Abstract: A coil that includes: a coil wire spirally wound along an axis; and an insulator that covers at least a portion of the coil wire. In a cross section including the axis, the insulator includes: a first insulation portion in contact with a first end surface of the coil wire on a first side in a direction of the axis of the coil wire, a second insulation portion in contact with a second end surface of the coil wire on a second side in the direction of the axis of the coil wire, and a third insulation portion between adjacent turns in the direction of the axis of the coil wire. At least one of a first thickness of the first insulation portion and a second thickness of the second insulation portion is thinner than half of a third thickness of the third insulation portion.

Abstract: A drop in the luminous efficiency of a light-emitting element and the occurrence of mounting problems for the light-emitting element can be prevented even in a configuration in which an ESD protection element is provided within a mounting substrate. A light-emitting device includes a light-emitting element and a mounting substrate, having a first surface on which the light-emitting element is mounted and a second surface that is opposite from the first surface, that includes a semiconductor-based electrostatic discharge protection element portion that is provided on the second surface side and is connected to the light-emitting element.
