WAVELENGTH CONVERSION MEMBER, LIGHT EMITTING DEVICE, AND METHOD OF MANUFACTURING LIGHT EMITTING DEVICE

摘要

Provided is a wavelength conversion member, a light emitting device, and a method of manufacturing the light emitting device, with which leakage of unconverted light and contamination of an upper surface of an electrode are prevented, and restriction on a position at which the electrode is to be provided on the light-emitting element is eliminated. The wavelength conversion member provided on a light extracting side of a light-emitting element having an electrode on the light extracting side and configured to convert a wavelength of outgoing light from the light-emitting element includes: a wavelength converting plate having a phosphor excited by the outgoing light, and a through-hole penetrating between a front surface and a back surface so as to correspond to the electrode; and a via electrode made of a conductive material filled in the through-hole, and having an upper surface exposed at the front surface of the wavelength converting plate.
