A pressure control valve structure includes a wall portion having a plurality of communication holes communicating with the internal space, a plurality of tubular portions surrounding the communication holes and extending outwardly from a wall surface of the wall portion as a proximal end, an elastic valve body disposed in each of the tubular portions and having a first end surface and a second surface opposite from the first surface, an outer peripheral wall surrounding the plurality of tubular portions collectively, and a cover fixed to the outer peripheral wall. The tubular portions are spaced from the cover. The tubular portions has an inner wall surface that includes an inclined surface that is inclined downwardly in a gravity direction from the proximal end of the tubular portion to a distal end of the tubular portion with a compression direction of the elastic valve body set extending horizontally.

Integrated devices comprising integrated circuits and energy storage devices are described. Disclosed energy storage devices correspond to an all-solid-state construction, and do not include any gels, liquids, or other materials that are incompatible with microfabrication techniques. Disclosed energy storage device comprises energy storage cells with electrodes comprising metal-containing compositions, like metal oxides, metal nitrides, or metal hydrides, and a solid state electrolyte.
