  • Publication number: 20240145153
    Abstract: An inductor component includes a base body including an insulator, an inductor wire extending inside the base body, extended electrodes connected to the inductor wire, each of the extended electrodes having a portion exposed to outside of the base body, and outer electrodes connected to respective ones of the extended electrodes. The base body, inductor wire, and extended electrodes form a component body. When a first sectional area is defined as an area of a section of the component body taken along a plane parallel to the bottom surface of the component body at an arbitrary position and when a second sectional area is defined as an area of another section of the component body taken along another plane parallel to the bottom surface closer to the bottom surface from the arbitrary position, the second sectional area is equal to or greater than the first sectional area.

  • Patent number: 11430713
    Abstract: A member to be fastened on one side of which a member to be fixed is placed; a plate-shaped holding spring member which is disposed on the member to be fixed on one side thereof opposite to the member to be fastened; a support which extends outward of an end part of a longitudinal central part of the plate-shaped holding spring member and which has a through hole formed therein; a supporting column which is provided on the support and bends toward the member to be fastened; a fixing screw hole which is provided in the member to be fastened and disposed at a position corresponding to the through hole of the support so as to have the same axial center as the through hole; and a fixing screw which is inserted into the through hole of the support and screwed to the fixing screw hole.
