An object of the present invention is to provide a sound-blocking sheet member that is relatively lightweight, has high sound-blocking performance overwhelming the law of mass action, and is excellent in terms of manufacturability and durability. The sound-blocking sheet member includes at least a sheet and a plurality of resonance portions. The resonance portion is provided in contact with a sheet surface of the sheet, and the resonance portion includes a weight portion and a base portion. The weight portion is supported by the base portion and has a larger mass than the base portion, and the weight portion has a penetration portion. The base portion is in contact with a surface on a resonance portion front end side of the weight portion and covers the weight portion.

The invention is intended to easily enhance both the stain-resistant property against water scale and the stain-resistant property against oily components, in sanitary ceramic wares and the like which are brought into contact with water containing soluble silica as well as oily components. The stain-resistant coating material of the invention contains a main agent formed from a perfluoropolyether, and a solvent including an alkane and an alcohol, while the alkane has mean molecular weight of 138 to 180 g/mol.

A RE-type oxide superconducting wire having excellent angular dependence for magnetic field of Jc is obtained by finely dispersing magnetic flux pinning centers into a superconductor. A mixed solution which comprises a metal-organic complex solution including a metal element which composes a RE-type oxide superconductor whose Ba content is reduced and a metal-organic complex solution including at least one or more kinds of metals which are selected from Zr, Ce, Sn, or Ti which has a larger affinity for Ba is coated onto an intermediate layer of a composite substrate, and the assembly is then calcined to disperse artificially and finely oxide particles (magnetic flux pinning centers) including Zr. Thus, the angular dependence for magnetic field (Jc/Jc) of Jc can be remarkably improved.
