Abstract: A cover material of the invention includes: a base member; a sealant layer; and an adherence prevention layer including particles and a binder used to adhesively fix the particles to the sealant layer, the particles having a mean particle diameter of 5 to 1000 nanometers.

Abstract: In an embodiment example of the present invention, an image sensor comprises a filter used for an extraction of a specific color component of an incident light, a light receiving element which observes the incident light via the filter, a compensating filter having a transmission restraining characteristic in a visible light wavelength range and a transmission characteristic in a wavelength range on a longer wavelength out of the visible light wavelength range, and a compensating light receiving element which observes the incident light via the compensating filter for compensating an observation result by the light receiving element.
