A light-emitting device of the present invention includes: a LED chip 10; a chip mounting member 70 having a conductive plate (heat transfer plate) 71 one surface side of which the LED chip 10 is mounted on and a conductor patterns 73, 73 which is formed on the one surface side of the conductive plate 71 through an insulating part 72 and electrically connected to the LED chip 10; and a sheet-shaped connecting member 80 disposed on the other surface side of the conductive plate 71 to connect the conductive plate 71 to a body of the luminaire 90 which is a metal member for holding the chip mounting member 70. The connecting member 80 is made of a resin sheet which includes a filler and whose viscosity is reduced by heating, and the connecting member 80 has an electrical insulating property and thermally connects the conductive plate 71 and the body 90 of the luminaire to each other.
