  • Coil Component
    Publication number: 20220277880
    Abstract: A coil component includes a bobbin, a magnetic core, a coil, and a cover member attached onto the bobbin along an attachment direction. One of the cover member and the bobbin has a spring piece. The spring piece elastically energizes the other of the cover member and the bobbin. The spring piece extends along the attachment direction and has one end, a contact part, an entering part, and a tip end. The other of the cover member and the bobbin has a convex part and a recessed part. The recessed part is closer to the tip end than the convex part. The contact part contacts and energizes the convex part. The entering part enters the recessed part. The spring piece is bent to generate an energizing force. The cover member energizes the bobbin upward at a contact position by the energizing force.
