PURPOSE:To obtain a prism-shaped chip inductor easily by winding a ceramic green sheet into a column shape once and then putting it in a die to form it into a prism shape by molding. CONSTITUTION:An end of a ceramic green sheet 1 is entwined on a winding core 5 of a small diameter and wound into a column shape by a method such as rotation of the winding core 5. As a result, a linear conductor 4 is wound spirally and a coil is formed. After wound into a column shape, the winding core 5 is pulled out. Next, the ceramic green sheet formed into a column shaped is put in a cavity of a bottom force 9 and is shaped into a prism by pressure of a top force 10. Then, the prism-shaped ceramic green sheet is put in a container and is calcined, after which external electrodes are applied to the both ends in a manner these are connected to lead electrodes 2 and 3. |
