    • A motor may include a stationary section and a rotating section. The stationary section may include a stator core having a plurality of teeth and a coil including a conducting wire wound around each tooth. The rotating section may include a plurality of magnets arranged radially inside the coil, a rotor core, and a magnet holder holding the magnets. Each magnet may have a circumferential end face at each of both end portions in the circumferential direction. The magnet holder may include a columnar portion axially extending between adjacent magnets, and a wall surface spreading in the circumferential direction from the columnar portion. The wall surface may come into contact with a surface arranged radially outside the circumferential end face of the magnet. The circumferential end face on at least one side of the magnet may face the columnar portion with a gap interposed therebetween in the circumferential direction.

    • A solar cell including a substrate 1, a nanopillar 11 having diameter D1 connected to the substrate 1, and a nanopillar 12 having diameter D2 connected to the substrate 1 is characterized in that D2 is greater than D1 in order to realize a solar cell having, as the surface structure, a nanopillar array structure with which it is possible to prevent reflection within the broad wavelength region of solar light. A nanopillar array structure 21 formed from two types of nanopillars having different diameters has a point of minimum reflectivity of a nanopillar array structure formed from the nanopillar 11 having diameter D1 and a point of minimum reflectivity of a nanopillar array structure formed from the nanopillar 12 having diameter D2 and therefore, is capable of preventing reflection within the broad wavelength region of solar light.
