Zusammenfassung:	The purpose is to provide a including wavelength conversion member by which sufficient total flux can be assured, particularly with a white LED of low color temperature, a method for manufacturing the same, a light-emitting device and a lighting fixture including the wavelength conversion member, and a resin composition. The problem is solved by a wavelength conversion member for converting the wavelength of at least a portion of incident light, and emitting exiting light of a different wavelength than the incident light, the wavelength conversion member characterized in that the wavelength conversion member has a planar structure including a phosphor for absorbing at least a portion of the incident light and emitting exiting light of a different wavelength than the incident light, and a resin for retaining the phosphor, at least a portion of the planar structure having total light transmittance of 30% to 70% inclusive. Le but de l'invention est de fournir un élément de conversion de longueur d'onde permettant de garantir un flux total suffisant, en particulier avec une DEL blanche d'une température de couleur faible, un procédé de fabrication associé, un dispositif émettant de la lumière et un appareil d'éclairage comprenant l'élément de conversion de longueur d'onde, et une composition de résine. Le problème est résolu à l'aide d'un élément de conversion de longueur d'onde pour convertir la longueur d'onde d'au moins une partie de la lumière incidente, et émettre de la lumière sortante d'une longueur d'onde différente de celle de la lumière incidente. L'élément de conversion de longueur d'onde est caractérisé en ce que l'élément de conversion de longueur d'onde a une structure plane comprenant un phosphore permettant d'absorber au moins une partie de la lumière incidente et d'émettre de la lumière sortante d'une longueur d'onde différente de celle de la lumière incidente, et une résine pour retenir le phosphore, au moins une partie de la structure plane ayant une transmittance de lumière totale de 30 % à 70 % inclus.
