Definitions

  • the lead conductors 27 electrically connect the first electrode layers 23a to 23d and the connection electrodes 25 provided in the porous body 10 to the external electrodes 21, and the lead conductors 28 connect the internal electrodes of the porous body 10 to each other.
  • the second electrode layers 24 a to 24 d and the connection electrodes 26 provided on the outer electrodes 21 are electrically connected to the external electrodes 21 . Therefore, the first electrode layers 23a to 23d and the connection electrode 25 constitute the first internal electrodes, and the second electrode layers 24a to 24d and the connection electrode 26 constitute the second internal electrodes.
  • a capacitor component 1 according to an embodiment of the present invention is more suitable for use at high temperatures than a capacitor component that uses a thick film resist as a dielectric.
  • a wall portion separating adjacent turns includes two or more through holes 11 along the radial direction of the circumferential groove (direction passing through the coil axis and perpendicular to the coil axis).

Abstract

Un composant de condensateur selon un mode de réalisation de la présente invention comprend : un corps principal poreux qui a une pluralité de trous traversants qui s'étendent dans une première direction ; une première électrode interne ; et une seconde électrode interne. Le corps principal poreux est pourvu d'une première rainure qui est formée de façon à s'étendre dans une deuxième direction qui est perpendiculaire à la première direction, tout en pénétrant à travers le corps principal poreux dans la première direction. Une première couche d'électrode, qui est contenue dans la première électrode interne, est enfouie dans la première rainure. Le corps principal poreux est pourvu d'une seconde rainure qui fait face à la première rainure, une partie paroi étant interposée entre celles-ci. Une seconde couche d'électrode, qui est contenue dans la seconde électrode interne, est enfouie dans la seconde rainure. La partie paroi contient au moins deux trous traversants parmi la pluralité de trous traversants du corps principal poreux dans une troisième direction qui est perpendiculaire à la première direction et à la deuxième direction.
