An electronic component capable of preventing the occurrence of magnetic saturation due to a magnetic flux surrounding each coil conductor and a method of manufacturing the electronic component are provided. Alternatively, a carbon monoxide selective oxidizing catalyst includes a carrier whose maximum pore diameter ranges from 0. The proxy to the host’s object model conforms to requirements of the MAF. The base, lid, and hinge may be manufactured from plastics or other conventional material for a while-in-use electrical device cover using conventional fabrication methods. According to the invention, gas modification efficiency can be remarkably improved.
