A method for manufacturing composite particles for an electrochemical element electrode containing: a slurry manufacturing step (S1) for obtaining an aqueous slurry composition containing an electrode active substance and a particle binding agent; a transfer step (S2) for transferring the aqueous slurry composition to a spraying machine; a pelletization step (S3) for obtaining granulated particles by spraying using the spraying machine, and drying; and a separation step (S5) for separating coarse particles from the granulated particles, the method including a first removal step (S4) for removing metal foreign bodies using magnetism from the granulated particles obtained in the pelletization step, and/or a second removal step (S6) for removing metal foreign bodies using magnetism from the granulated particles from which the coarse particles were removed by the separation step. |
