A terminal electrode connected to the vibrating electrode is formed at the end, and an external connection electrode made of a solder film is formed at the end of the protective substrate that does not face the piezoelectric substrate and corresponds to the terminal electrode. By joining at least the portions of the piezoelectric substrate and the protective substrate excluding the vibrating electrode with an insulating adhesive, a sealed vibration space is formed around the vibrating electrode, and the piezoelectric substrate and the protective substrate are bonded together. A chip-type piezoelectric resonator characterized in that a terminal electrode of a piezoelectric substrate and an external connection electrode of a protection substrate are electrically connected to each other by forming conductive films on both end faces of the piezoelectric resonator.
