More preferably, the distance y is 100 ⁇ m or less. This is because when the average distance y exceeds 100 ⁇ m, the function of firmly bonding the steel layer and the Al-containing metal layer is reduced, leading to peeling and cracking of the plating layer, and the corrosion resistance is also reduced. More preferably, the average interval y is 80 ⁇ m or less.

- the manufacturing method according to the embodiment of the present invention will be described later in detail.
- the thickness of the steel layer of the metal foil is 10 to 200 ⁇ m. In order to manufacture a foil having a thickness of less than 10 ⁇ m, it is necessary to carefully control a high-accuracy apparatus, resulting in high cost. On the other hand, if the thickness exceeds 200 ⁇ m, the weight of the metal foil becomes heavy, and the merit of using the foil cannot be sufficiently obtained. In order to reduce the weight of the substrate, the thickness is preferably 10 to 150 ⁇ m. In order to place a heavy object on the base material, the thickness is preferably 100 to 200 ⁇ m. It is most preferable that the thickness of the steel layer is 100 to 150 ⁇ m because both effects can be obtained simultaneously.

- a withstand voltage of 500 V or more can be ensured, and dielectric breakdown can be avoided. Even if dielectric breakdown does not occur, the presence of leakage current causes a decrease in photoelectric conversion efficiency of the solar cell module, but such leakage can be prevented by adopting the above structure.
- the method of measuring the thickness and composition of each layer described above is a method of analyzing while digging in the film thickness direction from the surface of the metal foil by a sputtering method, or performing line analysis or point analysis on the cut surface in the film thickness direction of the metal foil.
- the technique to do is effective. In the former method, when the measurement depth is increased, it takes too much measurement time, but in the latter method, it is relatively easy to measure the concentration distribution in the entire cross section, check reproducibility, and the like. If you want to improve the accuracy of analysis in line analysis or point analysis, it is also effective to narrow the analysis interval with line analysis or expand the analysis area with point analysis. is there.

Rolling. If the total rolling reduction is less than 50%, the Fe—Al alloy layer is not divided and cannot be made into a granular alloy. In order to control the equivalent sphere diameter of the granular alloy and the average interval to the target state, the total rolling reduction is preferably 65% or more. The upper limit of the total rolling reduction is 99% due to restrictions on the facility capacity. Moreover, if the thickness of the metal foil is less than 10 ⁇ m, the metal foil for the substrate is too thin and the strength is insufficient. On the other hand, if the thickness of the metal foil exceeds 250 ⁇ m, it is too thick and too heavy as a metal foil for a substrate.
- this second rolling process is a cold rolling of at least 3 passes, and the reduction rate of the second pass is higher than that of the first pass. It is preferable that the reduction rate of the third pass is lower than the second pass, and the reduction rate after the third pass is lower than the reduction rate of the third pass.

- the thickness of the Al-containing metal layer of the metal foil after the second rolling process or the skin pass rolling process is preferably 0.1 to 30 ⁇ m. If the thickness is less than 0.1 ⁇ m, a sufficient corrosion resistance effect cannot be obtained, and if it exceeds 30 ⁇ m, it is necessary to plate a large amount of Al, which increases the production cost.
