摘要： A manufacturing method of a coil component comprising the steps of: preparing a coil assembly body in which a coil is attached on a magnetic core and a mold body which is formed with a cavity portion in the inside thereof and which includes at least one opening portion, putting a viscous admixture including magnetic powders and thermosetting resin and the coil assembly body in the cavity portion, pushing the put-in viscous admixture in the mold body, and thermally-curing the pushed-in viscous admixture and forming a magnetic exterior body which covers the coil assembly body.

摘要： A manufacturing method of a coil component for forming a coil-assembly body in which a coil is mounted on a magnetic-body core, comprising the steps of: inputting the coil-assembly body and an admixture containing a magnetic powder and a resin into a container; applying pressure onto the admixture which is inputted into the container; depressurizing an air pressure of an environment, in which the admixture is placed, to become a negative-pressure lower than the atmospheric pressure at least during the pressurizing process in the step of applying pressure; applying vibration onto the admixture and filling the admixture in the container at least during the depressurizing process in the step of depressurizing; and curing the resin contained in the admixture for the integrated object of the admixture and the coil-assembly body which passed through the step of depressurizing and the step of applying vibration.

摘要： A terminal plate member on which a terminal of a coil component is mounted including: an annular frame having an inner peripheral edge; a pair of extension members extending from the inner peripheral edge of the annular frame toward an inner space of the annular frame member in a first direction; and a deformable section provided in the annular frame at proximal end of one of the pair of extension members, the deformable section having a more easily deformable property than other sections of the annular frame when force is applied. The deformable section is provided along at least an entire width in a second direction of the one of the pair of extension members. The second direction is perpendicular to the first direction.
