  • Patent number: 11948727
    Abstract: An inductor component and a method for manufacturing an inductor component that enables miniaturization of the inductor component. An inductor component includes an annular core; and a coil including a plurality of pin members and wound on the core with neighboring pin members connected to each other. A first pin member and a second pin member both adjacent to each other have a welded part in which an end face of an end part of the first pin member and a peripheral surface of an end part of the second pin member are welded to each other. The welded part is not provided on an outer side edge of the second pin member as viewed from a direction orthogonal to a first plane containing a center line of the end part of the first pin member and a center line of the end part of the second pin member.

  • Publication number: 20240077373
    Abstract: A force sensor module according to an embodiment of the present disclosure includes a plurality of force sensors. Each of the force sensor includes a plurality of sensor sections having force detection directions different from each other, and a flexible rubber member that is provided to cover the plurality of sensor sections. The rubber member is configured to transmit a force inputted from outside to the plurality of force sensors by deformation corresponding to the force.
