PURPOSE: Aramid fiber cord and a manufacturing method thereof are provided to offer good formability with a low initial modulus value while satisfying tenacity property required for general tire cord such as a heavy vehicle etc. CONSTITUTION: Aramid fiber cord includes aramid cabled yarn. The aramid cabled yarn has aramid single yarns which are respectively braided. The aramid single yanrs are Z-twisted aramid multifilament. The s-twisted aramid singe yarns is aramid cabled yarn. A first twist number is smaller than a second twist number. The first and the second twist numbers are 200 - 600 TPM. A manufactruing device for the aramid fiber cord includes a spinneret(100), a solidification tank(200), a first washing tank(300), a first washing roll, a drying part(500), a heat-treatment roll(610), and a winder(700) etc.
