The invention provides a holding member, a driving device, a pickup device and a disc device to improve coil sensitivity to a magnetic member. Provided is a holding member having a coil. The holding member is provided with a proximity promoting section which can bring the coil close to the magnetic member facing the coil. The proximity promoting section is a protruding section which protrudes toward the outside of the holding member main body from a reference surface section of the coil mounting section of the holding member main body provided with the coil. Magnetic field generated in the magnetic member is efficiently used, and coil sensitivity is improved. The driving device is provided with the holding member, the coil provided on the holding member and a magnetic member facing the coil. The pickup device is provided with the holding member, a lens provided on the holding member, the coil provided on the holding member and the magnetic member facing the coil.
