    摘要: An active layer (17) is provided so as to emit light having an emission wavelength in the 440 nm to 550 nm band. A first-conductivity-type gallium nitride semiconductor region (13), the active layer (17), and a second-conductivity-type gallium nitride semiconductor region (15) are arranged along a predetermined axis (Ax). The active layer (17) includes a well layer composed of hexagonal InxGa1-xN (0.16≦x≦0.4, x: strained composition), with the indium fraction x represented by the strained composition. The m-plane of the hexagonal InxGa1-xN is oriented along the predetermined axis (Ax). The well-layer thickness is between greater than 3 nm and less than or equal to 20 nm. Having the well-layer thickness be over 3 nm makes it possible to fabricate light-emitting devices having an emission wavelength of over 440 nm.
