PURPOSE:To provide a high permeability MnZn ferrite core with low variation at mass production. CONSTITUTION:On a baking case 1 that is made of a refractory material, a ferrite sheet 2 made of Japanese paper on which an MnZn ferrite material is stuck is laid. On the periphery of the ferrite sheet 2, ferrite blocks 3 are arranged, and in the recessed part that is formed by the ferrite sheet 2 and the ferrite blocks 3 an MnZn ferrite compacts to be baked are arranged, and laying the ferrite sheet 2 on it, the baking is performed. |
