PURPOSE:To obtain a coil suitable for driving a magnetic bubble memory, etc., whose floating capacity and high frequency loss are reduced, by matching center axes of plural coil elements as one body to adhere them, and connecting terminals of respective coil elements each other. CONSTITUTION:Plural coil elements 1 are united as one body by matching their center axes inside the coil elements to adhere them and terminals of respective coil elements 1 are electrically connected each other. For example 2 two-layer winding coils (1-a, 1-b) are united by matching their center lines to adhere them each other. The external layer terminal 3-a of the coil element 1-a and the internal layer terminal 2-b of the coil element 1-b are electrically connected in series at a connection part 7 or both the coil elements 1-a. 1-b are electrically connected in parallel to obtain a coil whose floating capacity between the coil layers 8 shown by a dotted line in the figure is reduced. |
