Zusammenfassung:Provided is a wavelength converting member which can reduce change in the light emission intensity over time as compared with conventional members and a method of producing the wavelength converting member. A wavelength converting member (1) includes a quantum dot layer (2) having quantum dots, barrier layers (3, 4) formed on at least both sides of the quantum dot layer (2). The moisture vapor transmission rate of the barrier layer is lower than 9 g/(m2·d). Thus, change in the light emission intensity over time can be effectively inhibited.
