To realize an LED package and an LED lighting device which efficiently radiate heat generated from an LED chip, improve the reliability, and achieve the size increase.
An LED package 100 includes: an LED chip 110; a supporting body 120 supporting the LED chip 110 on a placement surface 120a and formed of a ceramic; a metal film for heat radiation 130 formed on a rear surface 120b of the supporting body 120 and electrically insulated from a wiring pattern 160 on a circuit board 170; and conductor wirings 140 and 150 electrically connecting the LED chip 110 installed in the supporting body 120 with the circuit body 170. The metal film for the heat radiation 130 thermally connects the rear surface 120b of the supporting body 120 with the circuit board 170.
