An amorphous alloy magnetic core including a layered body in which amorphous alloy thin strips are layered one on another, the layered body having one end face and another end face in a width direction of the amorphous alloy thin strips, an inner peripheral surface and an outer peripheral surface orthogonal to a layering direction of the amorphous alloy thin strips, and a hole passing through from a part of the one end face as a starting point, the width direction corresponding to a depth direction of the hole.
