To secure the end part of a metallic filament taken up onto a reel, the take-up reel for metallic filament has a recessed portion (3) provided in the inside surface of a flange (2), the recessed portion (3) extending in the radial direction to the flange outer edge (2a); and a connecting portion (4) that straddles the recessed portion (3). A tabular end retaining member (5) having elasticity is fitted into the recessed portion 3. The base end portion (5b) of the end retaining member (5) is passed under the connecting portion (4) and butted up against the end surface (3a) of the recessed portion (3) on the winding drum side, and a space (A) is provided between the tip end portion (5a) of the end retaining member (5) and the flange outer edge (2a) to allow the end part of the metallic filament (W) to be caught therein. The end retaining member (5) is anchored to the connecting portion (4) through spot welding, using a welding portion (6) set in the vicinity of the base end portion.
