A connector pair includes a first connector, and a second connector electrically connected to the first connector. The first connector includes a first electrical contact part provided with a graphene film on a metal base material. The second connector includes a second electrical contact part electrically connected to the first connector via the graphene film. A contact area between the first electrical contact part and the second electrical contact part is smaller than an area of the graphene film coating the metal base material.

Connector and connector pair

A method of producing a composite nanoparticle (M-AO), having: generating, in an inert gas, an alloy (A-M) nanoparticle, which contains 0.1 at. % to 30 at. % of a noble metal (M), with the balance being a base metal (A) and inevitable impurities, and which has a particle size of 1 nm to 100 nm, to heat the alloy (A-M) nanoparticle and to bring the alloy (A-M) nanoparticle into contact with a supplied oxidizing gas during transportation of the alloy (A-M) nanoparticle with the inert gas, to oxidize the base metal component (A) in the floating alloy (A-M) nanoparticle, and to phase separate into the thus-oxidized base metal component (AO) and the noble metal component (M), to thereby obtain a composite nanoparticle (M-AO) having one noble metal particle (M) combined to the surface of a particulate base metal oxide (AO).
