The present invention relates to a Ti-V-Cr-Mn-Mg-based alloy for hydrogen storage and a method for manufacturing the same, and an object thereof is to provide a part of element V to a BCC-based solid solution hydrogen storage alloy containing Ti-V-Cr as a main element. The present invention provides a hydrogen storage alloy capable of increasing the amount of hydrogen occlusion and the amount of occlusion near room temperature by substituting Mn and adding Mg element thereto, and a method of manufacturing the same.;In the BCC-based hydrogen storage alloy, the hydrogen storage Ti-V- formed by adding 10-50 parts by weight of Mg to 100 parts by weight of a four-component alloy composed of Ti 0.34 V 0.26 Cr 0.38 Mn 0.02 It is characterized by Cr-Mn-Mg based alloy and its manufacturing method.;Hydrogen Storage Alloy, BCC Alloy, Hydrogen Storage, Hydrogen Release Rate, Hydrogen Release Temperature
