A three-dimensional molded circuit component, includes: a base member which includes a metal part and a resin part; a circuit pattern which is formed on the resin part; and a mounted component which is mounted on the base member, and is electrically connected to the circuit pattern. The resin part includes a resin thin film as a portion thereof, which includes a thermoplastic resin, of which a thickness is in the range of 0.01 mm to 0.5 mm, and which is formed on the metal part. The mounted component is arranged on the metal part via the resin thin film.

Three-dimensional molded circuit component

A method for producing a plated part, includes: forming, on a surface of a base member, a catalyst activity inhibiting layer containing a polymer which has at least one of an amide group and an amino group; irradiating with light or heating a part of the surface of the base member on which the catalyst activity inhibiting layer is formed; applying an electroless plating catalyst to the surface of the base member heated or irradiated with the light; and bringing an electroless plating solution into contact with the surface of the base member to which the electroless plating catalyst is applied, to form an electroless plating film at a light-irradiated portion or a heated portion of the surface.

Hyperbranched polymer, metal recovery agent, metal recovery method, and catalytic activity inhibitor

A magnetic recording medium comprising a nonmagnetic support and a magnetic layer formed on the support and containing a magnetic powder and a binder, wherein said magnetic powder comprises substantially spherical or ellipsoidal particles and at least one element selected from the group consisting of rare earth elements, silicon and aluminum, and has a FeNphase, an average particle size of 5 to 30 nm and an axis ratio (a ratio of a major axis to a minor axis) of 1 to 2. This magnetic recording medium achieves a high output and has excellent short wavelength recording properties, since it uses a magnetic powder having a very small particle size and has a very high coercive force and a saturation magnetization suitable for high density recording.

An infrared fluorescent particle comprising a functional group or a substance that is capable of binding to an analyte, wherein fluorescence at infrared wavelength is emitted from the particle upon exposure of the particle to excitation light at infrared wavelength. The infrared fluorescent particle of the present invention is capable of binding to the analyte. Due to a high penetration of the fluorescence and the excitation light into biological substances, the infrared fluorescent particle of the present invention can reduce an influence of luminescence, light absorption or light scattering which is occurred due to the analyte and the surrounding substances.
