Provided is a magnetic core having an appropriate range of permeability and a high magnetic flux density, thereby being configured to have a small phase difference and a small size. The magnetic core can be use for electric current sensors. The magnetic core is made of an amorphous alloy having a composition represented by the general formula: FeaMbSicBdM′e, in which M is at least one element that is selected from Ni and Co, and M′ is Cr, and a to e are atomic % and numbers satisfying 30≦a≦80, 1≦b≦50, 0.1≦c≦20, 0.1≦d≦20, and 0≦e≦10, respectively, and wherein the amorphous alloy has a magnetic flux density of 1.2 T to 1.7 T, and a permeability of 1,000 to 4,000.

Provided are an amorphous metal core that can minimize a core loss in which amorphous thin plate laminates are mutually combined by coupling protrusions and coupling recesses of assembly plates, an induction device, and a method of making the amorphous metal core. The amorphous metal core includes: a number of amorphous metal unit cores that include an amorphous thin plate laminate and a pair of assembly plates that are respectively laminated on the front and rear surfaces of the amorphous thin plate laminate, and are configured to have an I shape, respectively. The induction device includes: an amorphous metal core including a number of amorphous metal unit cores that are formed of an “I” shape, respectively; and at least one coil that is wound on at least one of the amorphous metal unit cores forming the amorphous metal core.
