Abstract:
A solid electrolytic multilayer capacitor comprising a multilayer capacitor element comprising a plurality of single plate capacitor elements comprisingan anode substrate comprising a plate-like valve-acting metal having on the surface thereof an oxide dielectric film layer, wherein an edge part of the anode substrate acts as the anode part and an area of said oxide dielectric film layer where a solid electrolyte layer and an electrically conducting layer are sequentially formed acts as a cathode part, said plurality of single plate capacitor elements are stacked such that the anode parts are stacked and fixed on a lead flame in the anode side while aligning the respective anode parts toward the same direction, wherein in the single plate capacitor element, a thickness of a distal end portion of the cathode part is larger than a thickness in a basal portion of the cathode part, the cathode parts are stacked and fixed on a lead flame in the cathode side through an electrically conducting adhesive layer to have an unfolded fan-like shape spreading out toward the distal end of the cathode part from the anode part side, and the plate-like valve-acting metal of each single plate capacitor element in the area having said solid electrolyte layer lies almost in parallel with the lead flame in the cathode side.
