The invention relates to a magnetoplumbate-type permanent magnetic ferrite and a manufacturing method thereof, which relate to the field of the permanent magnet. Main component of the magnetoplumbate-type permanent magnetic ferrite is expressed by the following formula: (1-x-y)Ca0.xSrO.(y / 2)R2O3.(n-z / 2-m / 2)Fe2O3.zMO.MzrO2, wherein R is of at least one element of La, Nd and Pr and contains La, M is selected from at least one element of Co, Zn, Ni, Mn and Cu and contains Co, and x, y, z, m and n respectively indicating the addition ratio of each main metal element calculated at mol. By adopting optimized formula and process design and adding less Zr element, the Zr element is introduced into ferrite lattice during the pre-burning process so as to inhibit the growth of abnormal crystal particle and to reduce the pores; moreover, N(CH2CH2OH)3 dispersing agent is particularly added, the appearance of the powder particles is effectively controlled, so the obtained crystal particles are moreuniform, the arrangement of the crystal structure is more compact, and the permanent magnetic ferrite material is obtained under the condition that substitute of the Co element is not high.
