PURPOSE:To prevent a combination of a bobbin and a terminal plate from becoming unstable easily due to unevenness of the forming, by combining the legs of the bobbin, around the upper portion of which a coil is wound, with the joining portions provided on the side faces of the terminal plate by means of acute projections which are formed outwardly at the joining portions. CONSTITUTION:Covered over a combination of a terminal plate 13 and a bobbin 12 is a core-holding mold 14, in which a core 15 with a center portion, having a cap shape, is screwed. Over the whole, a shield case 16 having an opening 16a at the upper portion is covered. In this constitution, since acute projections being provided at the joining portion 13a of the side faces of the terminal plate 13 are engaged with the legs 12b of the bobbin 12 and the combination is held in the core-holding mold 14 and the shield case 16, the position relation of the coil 11 and the core 15 remain constant without being affected by vibration from the outside. |
