Abstract:
1. A chip-type filter comprising: a laminated body including: a pair of positive electrode common terminals electrically coupled to the first positive electrode section of each of the at least one first solid electrolytic capacitor element of the first group and the second positive electrode section of each of the at least one second solid electrolytic capacitor element of the second group, respectively; a first negative electrode common terminal electrically coupled to the first negative electrode section of each of the at least one first solid electrolytic capacitor element of the first group; a second negative electrode common terminal electrically coupled to the second negative electrode section of each of the at least one second solid electrolytic capacitor element of the second group, and is electrically insulated from the first negative electrode common terminal; an insulating covering resin covering the laminated body in a state where a part of the positive electrode common terminals and a part of the first and second negative electrode common terminals are exposed; and an inductor section insulated from the respective negative electrode sections of the at least one first solid electrolytic capacitor elements of the first group and at least one second solid electrolytic capacitor elements of the second group and connecting the pair of positive electrode common terminals, wherein the insulating layer is one of a first insulating layer and a second insulating layer, the first insulating layer is disposed on a part exceeding 50% of a surface of the first negative electrode section of each of the at least one first solid electrolytic capacitor element of the first group on an opposite side to the first positive electrode section, the second insulating layer is disposed on a part exceeding 50% of a surface of the second negative electrode section of each of the at least one second solid electrolytic capacitor element of the second group on an opposite side to the second positive electrode section, the first negative electrode section of each of the at least one first solid electrolytic capacitor element of the first group has an exposed section that is electrically coupled to the first negative electrode common terminal, and the second negative electrode section of each of the at least one second solid electrolytic capacitor element of the second group has an exposed section that is electrically coupled to the second negative electrode common terminal.
