Abstract
A coil array component including an element assembly that includes a filler and a resin material, a first coil portion and a second coil portion that are embedded in the element assembly and that are composed of a first coil conductor and a second coil conductor, respectively, and four outer electrodes electrically connected to the first coil portion and the second coil portion. Also, the first coil conductor and the second coil conductor are covered with a glass layer.

A method for manufacturing a coil array component,
- the coil array component including
- an element assembly that includes a filler and a resin material,
- a first coil portion and a second coil portion that are embedded in the element assembly and that are composed of a first coil conductor and a second coil conductor, respectively, each of the first coil conductor and the second coil conductor being covered with a glass layer, a portion of the glass layer of the first coil conductor and a portion of the glass layer of the second coil conductor being arranged between the first coil conductor and the second coil conductor,
- a ferrite layer arranged between the glass layer of the first coil conductor and the glass layer of the second coil conductor, and
- four outer electrodes electrically connected to the first coil portion and the second coil portion, and
- the method comprising:
- forming a conductor paste layer of a photosensitive metal paste containing a metal that constitutes the first coil conductor or the second coil conductor by using a photolithography method on a substrate;
- forming a glass paste layer of a photosensitive glass paste containing glass that constitutes the glass layer so as to cover the conductor paste layer by using the photolithography method;
- forming in a region in which neither the conductor paste layer nor the glass paste layer is present on a substrate a shape-retaining paste layer of a photosensitive paste capable of being removed during firing;
- and
- forming the first coil portion and the second coil portion on the substrate by firing the substrate provided with the conductor paste layer, the glass paste layer, and the shape-retaining paste layer.
