PURPOSE: To keep a core member of laminated sheets of magnetic substance in a predetermined shape without requiring an exclusive lig or the like and maintain a magnetic gap formed between core members to have an accurate value.
CONSTITUTION: A core used combined two core members 101, 102 formed by laminated members A1, A2 of magnetic substance sheets with the end faces provided opposed with each other. The core members 101, 102 are inserted into non-magnetic cases B1, B2. The non-magnetic cases B1, B2 have group 4 respectively. The groove 4 has a flat bottom plate 41 and two side plates 42, 43. The core members 101 and 102 are inserted into the groove 4 so that the laminated surface orthogonally crosses the bottom surface 41 and aperture surface and becomes parallel with the side plates 42, 43.
