Claim 0:
1. A bonded body of an object to be bonded and a functional base material, wherein:
the functional base material is provided on a curved surface of the object to be bonded along the curved surface and/or on a smooth surface of the object to be bonded along the smooth surface, a peripheral gap part is provided between the object to be bonded and the functional base material on an inside of a peripheral distal-most end portion of a peripheral side surface of the functional base material and on a side opposing to the object to be bonded, and the peripheral gap part is filled with a holding member extending in a laminar fan shape from the peripheral side surface, along the curved surface and/or the smooth surface,
the functional base material has
an electrode including a first electrode arranged on a side not opposing to the object to be bonded, and
a second electrode arranged in a dielectric base, or has metal chips of a diverter strip arranged at an integrated dielectric base, or metal foil,

the gap part is formed with the object to be bonded and the functional base material, and/or the functional base material, the object to be bonded and an auxiliary bonding member, and/or the functional base material, the object to be bonded and a spacer member, on the inside of the peripheral distal-most end portion,
the second electrode or the metal chips or the metal foil, and the dielectric base, and also the holding member and the object to be bonded are bonded by molecular bond through addition coupling or substitution coupling with a monomolecular layer of a molecular adhesive or dehydration condensation coupling of a hydroxy group on the surface or a hydroxysilyl group subjected to the surface activation treatment, or by becoming a corona treatment surface, an ultraviolet treatment surface, an excimer treatment surface or an ITRO treatment surface, and
the functional base material is filled by the holding member with a lower peripheral part at the gap part from more peripheral side than the second electrode or the metal chips or the metal foil.
