An object of the present invention is to improve the light extraction efficiency from the light-emitting device and illumination device. The light-emitting device includes a plurality of semi-spherical member provided so as to overlap a plurality of the light emitting portion, and a plurality of light emitting members. A plurality of semi-spherical member has a plurality of semi-spherical member is provided so as not to form a space between them in the adjacent region. If the refractive index of the semi-spherical member, wherein n is the radius of the bottom surface of the hemispherical member b, the light emitting portion a radius (r) from the center of the bottom surface of the hemispherical member is provided in the interior of the b / n circle.
