Provided are a package and a method of manufacturing the package capable of suppressing corrosion of a bonding material and providing excellent airtightness, and to provide a piezoelectric vibrator, an oscillator, an electronic apparatus, and a radio-controlled timepiece. A bonding material formed on a front surface of a base substrate is anodically bonded to a frame region of a lid substrate. On the outer surface of a package, a protection film made of a material having higher resistance to corrosion than the bonding material is formed so as to cover at least the bonding material exposed between the base substrate and the lid substrate.
