In such a breathable container, a plurality of through holes are provided in the container main body, and a terminal and a gas vent valve are provided for different through holes among the plurality of through holes.

  The terminal is a rod-shaped conductor, and is fitted into one through-hole of the plurality of through-holes of the container main body, and protrudes to the outer space side (external space side) of the container main body. It has an internal terminal that is provided in the space and connects the external terminal and the capacitor element (see FIGS. 1 and 2 of Patent Document 1). On the other hand, the gas vent valve includes a sheet-like permeable rubber and a fixing means for fixing the permeable rubber to the through hole, and the through hole for the terminal among the plurality of through holes. It is provided by fitting into different other through holes.

The non-selective permeation sheet can be appropriately selected according to the properties of the selective permeation sheet to be overlaid. For example, a porous film made of polytetrafluoroethylene (PTFE), ceramic, metal, resin, etc. The thing comprised from a sheet material is mentioned. In particular, a porous membrane made of PTFE has high water repellency, high heat resistance, and high chemical resistance, and thus is preferable as a sheet material constituting a non-selective permeable sheet. The non-selective permeable sheet of this embodiment is composed of a porous membrane sheet material made of PTFE.

  In the breathable container A1 configured as described above, a predetermined member is accommodated in the internal space S of the main body B, and a container lid C is attached to the main body B so as to close the upper surface opening of the main body B. A terminal 1 (main body 2) is attached to the through hole C1 of the lid C (see FIG. 1). Specifically, the main body 2 of the terminal 1 has a lower end 2a on the inner space S side with respect to the container lid C so that the gas flow hole 2c communicates the inner space S and the outer space of the container main body A. The upper end 2b protrudes from the container lid C toward the outer space and is attached to the through hole C1. More specifically, the medium diameter portion 21b of the upper member 21 of the main body portion 2 of the terminal 1 is fitted in the small diameter hole C11 above the through hole C1. The large-diameter portion 21c of the upper member 21 and the large-diameter portion 22a of the lower member 22 in the main body portion 2 of the terminal 1 are fitted in the radial hole C12, and the small-diameter hole C11 below the through-hole C1 is fitted in the small-diameter hole C11.

In this state where the lower member 22 is fitted to the upper member 21, the gas permeable member 3 disposed in the recess 21 e of the upper member 21 has a lower surface (upper surface of the recess 21 e) and a lower surface of the large diameter portion 22 a of the upper member 21. It is positioned between the upper surface of the large-diameter portion 22a of the member 22 and is locked (for example, sandwiched or bonded by pressing) by the large-diameter portion 22a of the upper member 21 and the large-diameter portion 22a of the lower member 22. The gas permeable member 3 is provided in the gas flow hole 2c so as to intersect the central axis of the gas flow hole 2c (the upper gas flow hole 2c1 and the lower gas flow hole 2c2). More specifically, the gas permeable member 3 includes a gas flow hole 2c (specifically, one end (lower side) 2a opening of the upper gas flow hole 2c1 and the other end side (upper side) of the lower gas flow hole 2c2. 2) The opening 2b) is disposed in the recess 21e so as to cross the opening in the horizontal direction, and is sandwiched between the upper member 21 and the lower member 22. Thus, since the terminal 1 holds the gas permeable member 3, the container body A does not require a through hole for providing the gas permeable member 3 in addition to the through hole C 1 for providing the terminal 1.

  In such a breathable container A1, the terminal 1 is used by being electrically connected to an external element. During such use, the gas generated inside the breathable container A1 (specifically, the container body A) can be discharged to the outside through the gas permeable sheet of the gas permeable member 3 of the terminal 1.

The number of through-holes provided in the container main body A can be reduced as compared with the case where they are formed. Thereby, while being able to suppress that a foreign material mixes into the internal space S of the container main body A from a through-hole, the intensity | strength and design nature of the container main body A can be improved, and also the small size of the container main body A Can be achieved.

Can be configured. Furthermore, examples of the sheet material including the hydrogen permeable metal layer include a sheet material (metal foil) including only a hydrogen permeable metal layer, a sheet material obtained by depositing a metal layer on a base material layer such as a resin sheet, and the like.
