PROBLEM TO BE SOLVED: To provide a quantum interference device and an atomic oscillator which reduce a line width of an EIT signal and realize excellent frequency stability by stabilizing a magnetic field of an internal space of a gas cell, and further to provide an electronic apparatus and a movable body which are provided with the quantum interference device and are excellent in reliability.SOLUTION: An atomic oscillator comprises: a gas cell 31 having an internal space S filled with alkali metal atoms; a light emission section emitting excitation light LL including a resonance light pair resonating with the alkali metal atoms to the internal space S; a coil 35 provided so as to surround an outer periphery of the gas cell 31 with an axis of the excitation light LL as an axial direction; and a shield case 9 accommodating at least the gas cell 31 and the coil 35 and including a metallic material. The shield case 9 is constituted of a plurality of plate-like portions. A principal surface of one of two plate-like portions adjacent to each other out of the plurality of plate-like portions faces a lateral surface of the other thereof. |
