An angular velocity sensor is provided to reduce a long side of a mounting part by having a plurality of tuning-fork vibrators. An angular velocity sensor includes first and second tuning-fork vibrators(10a,10b), a mounting unit, a first wire(42a), and a second wire(42b). The first and second tuning-fork vibrators have a base unit and a plurality of arm units which are extended from the base unit. The mounting unit mounts the first and second tuning-fork vibrators. A front end unit of the arm unit of the first tuning-fork vibrator is opposite to a side plane of the second tuning-fork vibrator. The first wire, which connects the mounting unit to the first tuning-fork vibrator, is withdrawn to a width direction of the first tuning-fork vibrator. The second wire, which connects the mounting unit to the second tuning-fork vibrator, is withdrawn to a length direction of the second tuning-fork vibrator. A sound absorbing portion which is included in the mounting portion absorbs vibrations of the first and second tuning-fork vibrators.
