A quartz crystal device includes a package, a pedestal, and a crystal element. The pedestal is disposed in the package. The crystal element is bonded to the pedestal at four points. An angle formed by a center line connecting midpoints of both short sides of the crystal element and a straight line connecting a center point of the center line and each of bonding points is 22&#xb0; or more and 30&#xb0; or less.

Quartz crystal device, crystal unit, and crystal controlled oscillator

A pedestal on which a beveled blank is mounted is provided with a recess portion and an edge portion. The recess portion is provided in a central part of a surface of a pedestal body of the pedestal. The edge portion is adjacent to the recess portion to which the blank is fixed. The recess portion has a length in the short side direction of the pedestal body longer than that of the short side of the blank.

Pedestal mounted with a blank, crystal unit, and oscillator

A pedestal for a vibration element includes a main body that includes two connection portions, two clearance portions, a mounting portion, and arm portions. The two connection portions are formed along long sides of the main body and contact the base plate. The two clearance portions are formed on insides of the main body with respect to the connection portions and formed along the long sides. The mounting portion is located between the two clearance portions. The vibration element is mounted to the mounting portion. The arm portions are formed on four corners of the main body and connect the mounting portion to the connection portions. A metal pattern is connected to an electrode formed on the vibration element. The metal pattern is formed to connect the mounting portion, the arm portions, and the connection portions.

Pedestal for vibration element, resonator, and oscillator

To reduce interference between wiring patterns at an oscillator that outputs a plurality of oscillation signals. An oscillator includes an IC configured to output a plurality of oscillation signals using a crystal resonator, and a base plate connected to the IC. The base plate includes a crystal resonator land and a crystal resonator land that are electrically connected to the crystal resonator, a power source land electrically connected to a power source, and a first output land positioned between the crystal resonator land and the power source land to output a first oscillation signal from the IC to an outside, and a wiring pattern from the first output land passes through between the crystal resonator land and the crystal resonator land.
