1. One or more composite particles for an electrochemical device each comprising: a core particle; and a shell portion at least partially covering an outer surface of the core particle, wherein
the core particle contains a melamine compound represented by the following formula (I), where each A represents, independently of one another, a hydroxyl group or —NR1R2, where R1 and R2 each represent, independently of each other, a hydrogen atom, a hydrocarbon group, or a hydroxyl group-containing hydrocarbon group; when more than one R1 is present in formula (I), each R1 may be the same or different; and when more than one R2 is present in formula (I), each R2 may be the same or different,
and the shell portion contains an inorganic material.
