Beschreibung
Zusammenfassung:	A gaschromic light-modulation element according to the present invention includes a light-modulation substrate having a light-modulation portion on one principal surface of a first transparent substrate; and a second transparent substrate which is arranged so as to face the light-modulation part of the light-modulation substrate. The light-modulation portion includes a light-modulation layer, the light transmittance of which is reversibly changed by hydrogenation and dehydrogenation. At least one of the first transparent substrate and the second transparent substrate is flexible. A plurality of dot-shaped spacers are arranged between the light-modulation part and the second transparent substrate. It is preferable that the number density of the spacers is 70 to 15000 pieces/m2.
