PROBLEM TO BE SOLVED: To provide a coil part wherein the manhour required to fasten its cores to its bobbin is not altered in comparison with conventional cases and the accuracy required to attach its cores to each other is increased to an accuracy not smaller than conventional cases. SOLUTION: A closed magnetic-circuit type coil part comprises a coil portion formed by winding a wire around a bobbin and a pair of cores 1A, 1B integrated into the coil portion. The coil part has an engagement shape for engaging cores on a plane where the cores are brought into contact.
