Object of the present invention is to obtain a Nb.sub.3 Al group superconductor having a high critical current density under a whole range of magnetic field from low to high such as 20 T level, manufacturing methods thereof, a Nb.sub.3 Al group superconducting precursory composition, and a magnet for high magnetic field. In a process for manufacturing Nb.sub.3 Al phase by a diffusion reaction of Nb.sub.2 Al phase and Nb phase, a part of the Nb.sub.2 Al phase is remained and dispersed in the Nb.sub.3 Al phase homogeneously as for magnetic flux pinning centers for a high magnetic field. As for a method for dispersing the Nb.sub.2 Al phase homogeneously, a Nb.sub.3 Al group superconducting precursory composition obtained by dispersing Nb particles and Nb.sub.2 Al ultrafine particles by a mechanical alloying method is used, and further, by a conventional method for generating Nb.sub.3 Al phase by a diffusion reaction of Nb and an aluminum alloy, the object of the present invention can be achieved. In accordance with the present invention, a high magnetic field such as 20 T level which has never been achieved with only superconductor at 4.2K can be generated economically with a more compact apparatus than ever, and a coil for generating a high magnetic field can be manufactured with only the Nb.sub.3 Al group superconductor. Therefore, the present invention is significantly effective for a nuclear fusion apparatus of a magnetic confinement type.

An electrode for a lithium-ion secondary battery includes a collector of copper or the like, an electrode material layer being form on one surface and both surfaces of the collector and including an active material and a binder, and a binder-rich layer being formed in a dot shape or a stripe shape with a predetermined interval in the interface between the collector and the electrode material layer and having a binder concentration higher than that of the electrode material layer. Accordingly, a concentration gradient of the binder is provided to the surface of the collector. By arranging the binder-rich layer at a predetermined interval, it is possible to improve the adhesiveness between the collector and the electrode material layer due to an anchor effect and to guarantee conductivity between the collector and the electrode material layer.
