A pointing device including an operating section shiftably supported on a base section, a magnet carried on the base section or the operating section, and a magneto-electro transducer carried on the other close to the magnet. A first part securely holding one of the magnet and the magneto-electro transducer and shiftably supported on the base section in a horizontal direction relative to the base section, and a second part connected to and elastically biasing the first part towards a home position in a horizontal shifting range when the first part is horizontally shifted along the base section. The second part integrated with a major portion surrounding a circumference of the first part that has a first connecting portion connected to the first part and a second connecting portion connected to the base section, and exerting an even elastic biasing force irrespective of a shifting direction of the first part.
