  • Patent number: 11211188
    Abstract: In a stepwise structure formed in a multilayer coil component, a difference occurs in a shrinkage amount between a maximum film thickness portion in which the number of layers is large and a minimum film thickness portion in which the number of layers is small due to portions different in the number of layers of coil parts (that is, upper coil part, lower coil part, and connecting part) adjacent to each other like the maximum film thickness portion and the minimum film thickness portion, readily causing a crack by an inner stress due to the difference in the shrinkage amount. In a multilayer coil component according to the present disclosure, a stress relaxation part overlapping with a maximum film thickness portion whose shrinkage amount is large is provided to relax inner stress in a stepwise structure, resulting in prevention of a crack.
