The adhesive strength of the adhesive strength between the drum-shaped core 1 and the adhesive 3
It is determined by the lowest of the breaking strength of itself and the adhesive strength between the adhesive 3 and the electrodes 2a and 2b. Above all, since a constant space is required between the electrodes 2a and 2b, the adhesive area between the adhesive 3 and the electrodes 2a and 2b is small, and when foreign matter such as air or oil enters between them, ,
The adhesive strength is extremely reduced, and the drum-shaped core 1 is connected to the electrode 2a.
It had a defect that it was peeled off more than 2b.

込ませる方法としたものである。Means for Solving the Problems In order to solve this problem, a method for manufacturing a coil component according to the present invention is a drum type in which an adhesive is applied in advance on a lower surface so as to straddle electrodes arranged at a constant interval. Place the core on the surface of the electrode and press the adhesive overflowing on the back surface of the electrode from the back surface to the back surface of the electrode at the backup part, or wrap both sides of the electrode with the adhesive supplied to the back surface of the electrode. It was done.
作 用 上記方法によると、接着剤が電極の上面と下面とに渡っ

度を高くすることができる。Operation According to the above method, since the adhesive can be formed over the upper and lower surfaces of the electrode, even if there is peeling between the electrode and the adhesive, the adhesive acts as a wedge and adheres to the drum core. The peeling strength between the drum-shaped core and the electrode can be increased by not peeling the drum-shaped core from the electrode until the agent is peeled off or the adhesive is broken.
