An electrolytic capacitor includes an anode body, a dielectric layer covering the anode body, a first solid electrolyte layer covering the dielectric layer, and a second solid electrolyte layer covering the first solid electrolyte layer. The first solid electrolyte layer contains a first conductive polymer including polythiophene as a basic skeleton. The second solid electrolyte layer contains a second conductive polymer including polypyrrole as a basic skeleton. A conductivity of the first solid electrolyte layer is less than or equal to 2 S/cm.

Electrolytic capacitor and method for producing same

An electrolytic capacitor includes an anode body, a dielectric layer that covers the anode body, a first solid electrolyte layer that covers the dielectric layer, and a second solid electrolyte layer that covers the first solid electrolyte layer. The first solid electrolyte layer contains a first conductive polymer that includes polypyrrole as a basic skeleton. The second solid electrolyte layer contains a second conductive polymer that includes polythiophene as a basic skeleton. The second solid electrolyte layer has a thickness of 1 μm or more.

A contact device includes a pair of fixed contacts, a movable contactor, a contactor holder, a movable shaft, and a base. The pair of fixed contacts are aligned in a first direction. The movable contactor comes into or out of contact with the pair of fixed contacts in a second direction orthogonal to the first direction. The contactor holder holds the movable contactor. The movable shaft moves the contactor holder in the second direction so that the movable contactor comes into or out of contact with the fixed contacts. The base accommodates the fixed contacts, the movable contactor, and the contactor holder. The base has a projection projecting from a position opposing the contactor holder in a third direction orthogonal to both the first and second directions.

Contact device and electromagnetic relay

A contactor includes a pair of fixed contacts, a movable contact element configured to contact the pair of fixed contacts and to be separated from the pair of fixed contacts, a movable shaft configured to move in an axial direction as to cause the movable contact element to contact the pair of fixed contacts and to be separated from the pair of fixed contacts, and a partition-wall component disposed opposite to the pair of fixed contacts with respect to the movable contact element. The first partition-wall component includes a partition wall provided around the movable shaft. The first partition wall is configured to move synchronously with at least one of the movable contact element and the movable shaft.
