Method of producing light-emitting device and light-emitting device

A method of producing a light-emitting device, comprising:

• Preparing a plurality of light emitting elements each including element electrodes in a pair;
• arranging the plurality of light-emitting elements with the element electrodes in a pair of each of the plurality of light-emitting elements exposed from a sealing member;
• before a base electrode film is formed on the element electrodes of each of the plurality of light-emitting elements that are sealed with the sealing member, forming a protection film at a position corresponding to a position where the base electrode film is to be formed on the sealing member and on portions of the element electrodes except surfaces of the element electrodes exposed from the sealing member;
• forming the base electrode film on the element electrodes of each of the plurality of light-emitting elements;
• forming a resist mask on the base electrode film at a position where the base electrode film is divided into portions corresponding to a P electrode and an N electrode that are the element electrodes in a pair;
• forming metal plating for external connection electrode on the base electrode film at a position where the resist mask is not formed;
• removing the resist mask;
• and
• forming external connection electrodes in a plurality of pairs by etching the base electrode film at a position where the resist mark has been removed by using the metal plating for external connection electrode as a mask, the external connection electrodes in each pair being electrically divided into a P electrode and an N electrode and formed at positions where the external connection electrodes are electrically connected to the element electrodes in a pair of each of the plurality of light-emitting elements.
