A choke includes a base body, a plating layer and at least a coiled wire. The base body is a solid conductor with a cylindrical reel between an upper plate and a base bottom. The base bottom at two lateral sides thereof extends downward a base foot respectively and at least one of the base feet at an inner side thereof close to a support foot, which extends downward. A wire groove is formed between the base foot and the support foot. The plating layer is a conductor and plated on at least a pair of corners formed by the base feet, the support feet and the wire groove. The coiled wire is a metal wire with an outer insulation, which is wound up the reel with two wire ends thereof being connected to the plating layer.
