The objective of the present invention is to provide: a light-emitting device having a circuit pattern having superior electrical conductivity and thermal conductivity and has a suppressed deterioration of an optical semiconductor element during the production process; and a method for producing the light-emitting device stably and conveniently without imparting thermal damage to the optical semiconductor element. The light-emitting device has an optical semiconductor element, a circuit pattern, and an insulating substrate, and is characterized by the optical semiconductor element and the circuit pattern being electrically and/or thermally connected, the circuit pattern being provided on the insulating substrate, the circuit pattern being formed by means of sintering silver nanoparticles, and the silver nanoparticles being obtained by the thermal decomposition of a mixture containing an amine (A) having an amino group and an aliphatic hydrocarbon group, and a silver compound (B). |
