Abstract: An exterior material for a power storage device, the exterior material being constituted by a laminated body that includes at least a base material layer, a barrier layer, and a heat-sealable resin layer in this order from the outer side. The heat-sealable resin layer is formed from a polybutylene terephthalate film. The exterior material has a water-absorbing layer on the inner side than the barrier layer, and that contains a water-absorbing agent.

Abstract: A resin film for a power storage device that is arranged between an exterior material of a power storage device and a power storage device element, the resin film for a power storage device including a water absorbent.

Abstract: A ceramic electronic component includes: a ceramic body having a first surface; an external electrode disposed at least on the first surface; an internal electrode disposed inside the ceramic body; and a connection conductor connected to the external electrode and extending through a surface or an interior of the ceramic body to electrically connect to the internal electrode. The external electrode includes an overhanging portion extending laterally from its portion connected to the connection conductor. At least a portion of the overhanging portion is a peeled portion peeled off from the ceramic body.

Abstract: A multilayer ceramic electronic component includes an electronic component element including a ceramic layer and an inner conductor, and outer electrodes disposed on the surface of the electronic component element. The outer electrodes include a first layer disposed on the surface of the electronic component element, and a second layer disposed on the first layer. The first layer includes an oxide of at least one of elements of the ceramic layer. The second layer does not include oxides of elements of the ceramic layer.

Abstract: A monolithic ceramic electronic component includes at least two types of stacked ceramic layers having different dielectric constants and also includes internal electrodes partially disposed along boundaries between the ceramic layers having different dielectric constants. The internal electrodes include an additive component common to a component included in at least one of the ceramic layers adjacent to each other with the internal electrodes placed therebetween.
