PROBLEM TO BE SOLVED: To provide a light transmissive conductor which is constituted of a conductive material composed of a carbon nano linear structural body such as carbon nano tube, and for manifestation without damaging its light transmissivity and electric conductivity, its manufacturing method easy to scale up, a static elimination sheet using it, and an electronic device. SOLUTION: By immersing a light transmissive support body 3 into a dispersion liquid of carbon nano tube (CNT), making CNT adsorbed on its surface, evaporating a solvent after washing, and fixing the adsorbed CNT, the directly bonded conductive material 2 to the light transmissive support body 3 is formed. Since the conductive body 2 is formed only by carbon nano tube 1 and the carbon nano tube 1 is two-dimensionally integrated while contacting together at its one part, it is high in light transmissivity. Moreover, mutually contacting carbon nano tubes 1 are high in conductivity since they are directly bonded. It is better to carry out a treatment of improving affinity against the CNT on a surface of the support body 3 in advance. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a wiring circuit board which improves heat dissipation and can easily recognize dislocation of an electronic component, and to provide a method of manufacturing the wiring circuit board. SOLUTION: A rectangular mounting region S is arranged in an almost center of one face of an insulating layer 1. A plurality of conductor patterns 2 are formed so that they extend from an inner side to an external side of the mounting region S. A cover insulating layer 4 is formed to cover a plurality of the conductor patterns 2 at a periphery of the mounting region S. The electronic component 5 is mounted on the insulating layer 1 so that it is overlapped with the mounting region S. A metal layer 3 is arranged on the other face of the insulating layer 1. Rectangular openings 3a to 3f are formed on the metal layer 3 so that they follow a pair of long sides and a pair of short sides of the mounting region S. The openings 3a to 3f face part of a terminal part 21 of each conductor pattern 2 across the insulating layer 1. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a template for forming solder bumps, a method of manufacturing the template, and to provide a method of inspecting the solder bumps by using the template. SOLUTION: The template 20 for forming the solder bumps can include a transparent substrate 22 on which a plurality of cavities 22a are formed at an upper surface thereof, and a light-reflective film 24 and a protection film 26 formed on the lower surface of the transparent substrate 22. When a nozzle is brought into close contact with the template 20 to inject molten solder into the cavities 22a, damage to the template 20 may be prevented by the light-reflective film 24 and the protection film 26. Thereby, the lifetime of the template 20 may be sharply extended. An inspection step of solder bumps formed in the cavities 22a of the template 20 can be easily performed by analyzing light reflected by the light-reflective film 24. COPYRIGHT: (C)2009,JPO&INPIT
