The invention relates to a phosphor with garnet structure and a light-emitting device comprising the phosphor, wherein the phosphor includes the following components in percentage by weight: 38.47-45.19% of Y element, 9.49-22.09% of Al element, 2.06-24.31% of Ga element, 27.3-32.04% of O element, 0.43-1.46% of Ce element. In the phosphor particles, the shortest distance from the surface of one side of the particle to the surface of the opposite side through the centroid of the particle is defined as R, the longest distance is R1, and 5 μm≤R≤40 μm; any distance from the particle surface to the centroid is r, and 0<r<½R; and the space with the distance from the particle surface to the centroid direction being less than or equal to r is defined as r.
