A direct-current electric motor (an electrically powered machine) is a 3-pole brush-equipped direct-current electric motor which is provided with an armature (a rotor), a field element (a stator), a shaft, a commutator, a brush, a bracket, and an end plate. Of these, the armature (an armature) is provided with a dust core configured with a compressed powder compact formed of magnetic powder, and a coil buried in the dust core. On the other hand, the field element is provided with a field magnet which generates a magnetic flux, and a yoke housing which supports the field magnet and also functions as a housing.

Magnetic powder dust core with entirely buried coil or magnet

A method of manufacturing a vibrator which includes a method of manufacturing a wiring board includes disposing one granular conductor within each of through holes of a ceramic substrate having the through holes formed therein, supplying a glass paste into the through holes, baking the glass paste, forming an electrode, and disposing a vibrator element and a lid. When a maximum diameter of the granular conductor is set to dand a minimum diameter of each of the through holes is set to d, d/dis preferably equal to or greater than 0.8 and equal to or less than 1.
