ABSTRACT:
A hermetically sealed structure in which a base substrate31and a lid33are hermetically sealed, the base substrate serving as a part of a containing body for uniformly forming or bonding an electronic part, the lid being a lid body to be hermetically bonded to the base substrate, is structured as follows: the lid is made from a material, through which light passes; as a metal layer25of at least a sealing portion of the lid a platable layer22for performing plating and a bonding layer24made from gold, the bonding layer being formed closer to the front side than the platable layer are formed; and the lid is structured so as to be bonded to the base substrate31by an Au—Ge alloy.
