Abstract: Provided is a method for producing carbon nanotibers having excellent conductivity, crystallinity and dispersibility. A method for producing carbon nanofibers, which uses an activated species mainly composed of cobalt as a catalyst, while using carbon monoxide as a carbon source. The catalyst is obtained by having a carrier, which is composed of an oxide having a specific surface area of 0.01-5 m2/g and containing magnesium, support 3-90% by mass of the activated species. By controlling the reaction temperature, the carbon monoxide partial pressure and the gas flow rate of the carbon monoxide, CNF having more excellent conductivity, crystallinity and dispersibility can be produced, thereby obtaining carbon nanofibers having excellent conductivity, crystallinity and dispersibility.

Abstract: A buckle includes a male member and a female member. The male member includes: a base; a pair of legs that project from the base; engaging portions that are provided on the legs to be engageable with the female member; and a linking body that links the pair of legs. The linking body includes a curved portion that is curved such that the middle thereof is closest to the base. A pair of projecting portions that are substantially parallel with an insertion direction of the male member extend from the base to be disposed outside the curved portion such that the curved portion is interposed therebetween. With this arrangement, the linking body for linking the pair of legs can be disposed with less possibility that other objects are caught in a space in the male member and without increasing a length dimension in the insertion direction more than necessary. The male member can be stably held relative to the female member against a torsion force.
