Manufacturing method of end-sealing-free laminated inductor and end-sealing-free laminated inductor

The invention discloses a manufacturing method of an end-sealing-free laminated inductor and the end-sealing-free laminated inductor. According to the manufacturing method of the end-sealing-free laminated inductor, internal electrodes are formed on the substrate by adopting an alternate printing and exposure development process, so that the internal electrodes are sequentially connected and spirally stacked to form a laminated structure with a first end electrode and a second end electrode, the opposite area of two electrode plates of the end electrodes can be reduced, the parasitic resistance of the end electrodes and the parasitic capacitance generated by the internal electrodes are reduced, and the quality factor and the high-frequency characteristic of the laminated inductor are improved. 本发明公开了一种免封端积层电感器的制作方法及免封端积层电感器。所述免封端积层电感器的制作方法通过采用交替印刷和曝光显影工艺在基板上形成内部电极，使内部电极依次连接并螺旋堆叠形成具有第一端电极和第二端电极的积层结构，能够缩小端电极两极板的正对面积，降低端电极的寄生电阻和内部电极产生的寄生电容，实现提高积层电感器的品质因数和高频特性。
