<P>PROBLEM TO BE SOLVED: To provide a light emitting device which prevents a sealing resin from intruding into through holes and is easily manufactured. <P>SOLUTION: A light emitting device 20 includes: a circuit board 11; an LED element 13 placed on electrode patterns 14, 24 formed on an upper surface of the circuit board 11; and a sealing resin 16 provided so as to coat the LED element 13. The light emitting device 20 is mounted so as to emit light in parallel to a mother board 18. In the light emitting device 20, the circuit board 11 has recessed electrodes 15a, 25a provided on a connection surface with the mother board 18 and through holes 17, 27 electrically connecting the recessed electrodes 15a, 25a with the electrode patterns 14, 24. The through holes 17, 27 are filled with conductive members 17a, 27a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
