    Abstract: A coil component includes a magnetic portion that includes metal particles and a resin material, a coil conductor embedded in the magnetic portion and having a core portion, and outer electrodes electrically connected to the coil conductor. The magnetic portion includes a magnetic outer coating and a magnetic base having a protrusion portion. The coil conductor is disposed on the magnetic base such that the protrusion portion is located in the core portion. The magnetic outer coating is disposed so as to cover the coil conductor, and the bottom surface of the magnetic base includes a recessed portion in an area opposite to the protrusion portion.

    Abstract: To suppress deformation of a mounting portion, a coil component includes a drum core including a winding core portion, a first flange portion, and a second flange portion. The coil component includes a first metal terminal. The first metal terminal includes a joining portion, a mounting portion, and an extending portion. A first wire end of the first wire is connected to a surface of the joining portion facing a first positive direction. The mounting portion is located closest to the first positive direction in the first metal terminal. The extending portion connects the mounting portion and the joining portion. The extending portion includes a second portion having a thickness dimension smaller than the thickness dimension of the mounting portion.

    Abstract: A coil component includes a drum core including a winding core portion, first and second flange portions, a first metal terminal attached to the first flange portion, and a first wire. The first flange portion is connected to a first end of the winding core portion in a direction along a central axis of the winding core portion. A first connection end of the first wire is joined to the first metal terminal, which has a bonding portion that is fixed to an outer end surface. The bonding portion has a facing surface and a recess that is recessed with respect to the facing surface and accommodates an adhesive. When viewed in a direction along a central axis, an area of a region of the recess facing the outer end surface is equal to or larger than an area of the facing surface.

    Abstract: An inductor is provided so that reduction in DC superposition characteristics can be suppressed even when a filling rate of a magnetic powder is increased. The inductor includes a coil including a winding portion and a pair of extended portions extended from the winding portion, and a body having the coil embedded therein and containing a magnetic powder containing a first magnetic powder and a second magnetic powder, in which an average particle diameter of the first magnetic powder is larger than an average particle diameter of the second magnetic powder. In a cross section of the body including a winding axis of the winding portion and extending in a long side direction of the body, Voronoi partition is performed with a center of gravity of each magnetic powder as a generating point. When a standard deviation of an area of a Voronoi partition region with a magnetic powder having a particle diameter of equal to or more than 6 μm as a generating point is calculated, the standard deviation is equal to or less than 300.
