INDUCTOR COMPONENT AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2019/004038

A1

The purpose of the present invention is to suppress a decrease in reliability due to miniaturization of an inductor component. An inductor component comprises: a coil portion (11) having a lead wire (12) wound therearound; a lead-out portion (13) at which an end portion of the lead wire is led out; a connection line portion (16) to which the lead-out portion is connected; an outer terminal portion (17) integrally formed with the connection line portion; and a mold body (24) which is made of magnetic material and in which the coil portion and the connection line portion are embedded. The connection line portion has a shape extending along the lead-out portion, and includes a pair of first bonding pieces (21) between the coil portion and a terminal (14) of the lead-out portion, the pair of first bonding pieces (21) extending from both sides of the connection line portion in mutually opposite directions. The pair of first bonding pieces have distal end sides thereof respectively folded toward a part of the lead-out portion on the opposite side from the connection line portion. The lead-out portion and the connection line portion are connected by means of fusion bonding between the part of the lead-out portion on the opposite side from the connection line portion and a distal end part of the first bonding piece, whereby the terminal of the lead-out portion and the connection line portion are fusion-bonded and connected.
