This split core unit (30) has a split core (31), a coil (5), and an insulation member for insulating the split core (31) and the coil (5). The insulation member has end face insulation members (4). Each of the end face insulation members (4) has a first groove (4k) provided in a central region in the peripheral direction of an outer peripheral surface and extending in a straight line in an axial direction. A yoke part (31y) of the split core (31) has a second groove (31k) provided in a central region in the peripheral direction of an outer peripheral surface and extending in a straight line in an axial direction across the entire length of the split core (31). The first groove (4k) of each of the two end face insulation members (4) and the second groove (31k) of the split core (31) communicate with each other. The two first grooves (4k) appear overlapped with the second groove (31k) when viewed in the axial direction.
