Surface mount coil component
First Claim
1. A surface mount coil component comprising a winding wire, a core and a metal plate terminal, wherein said metal plate terminal integrally includes a fixing part which is bonded and fixed to said core, a joint part to which an end of said winding wire is bonded by thermo-compression bonding, and a mount part which is connected to an external circuit, the fixing part is integrally included between the joint part and the mount part, and a sectional reduced portion is formed between the joint part and the fixing part.

Abstract
An object is to provide a highly reliable surface mount coil component quickly and reliably forming thermo-compression bonding on an occasion of thermo-compression bonding by a heater chip, and reliably fixing the metal plate terminal, in a surface mount coil component having thermo-compression bonding of a winding wire and a metal plate terminal. In a surface mount coil component including a winding wire 2, a core 1 and a metal plate terminal 3, the metal plate terminal 3 integrally includes a fixing part 3b which is bonded and fixed to the core 1, a joint part 3a to which an end of the winding wire is bonded by thermo-compression bonding, and a mount part 3c which is connected to an external circuit, the fixing part 3c is integrally included between the joint part 3a and the mount part 3b, and a sectional reduced portion 5 is formed between the joint part 3a and the fixing part 3b.
