Document Type and Number:
WIPO Patent Application WO/2022/085552
Kind Code:
A1
Abstract:
A stacked coil component (1) comprises a stack (10) in which a plurality of insulating layers (41, 42, 43, 44) are stacked together and which incorporates a coil (30), and external electrodes (21, 22) provided on the outer surface of the stack (10) and electrically connected to the coil. In the stacked coil component (1), the coil (30) is formed of a plurality of coil conductors (31, 32) which are stacked together with the insulating layers (41, 42, 43, 44) and are connected together with a connecting conductor (33) therebetween. In a connecting portion (34) in which the first coil conductor (31) and the second coil conductor (32), which are the coil conductors adjacent to each other, are connected together with the connecting conductor (33) therebetween, the conductor width of the connecting conductor (33) is smaller than the conductor width of the first coil conductor (31), and the conductor width of the second coil conductor (32) is smaller than the conductor width of the first coil conductor (31).
