    • PROBLEM TO BE SOLVED: To reduce a manufacturing time and manufacturing costs by manufacturing a circuit board by a simple step.SOLUTION: The circuit board comprises: a substrate 2 formed in a flat plate shape and having a wiring formation surface; primer resin layers 3, 3... formed on the wiring formation surface of the substrate and having a predetermined adhesive force against the substrate; and wiring layers 4, 4... formed on the primer resin layer. The wiring layer is formed by removing portions contacting the wiring formation surface of the substrate among conductive inks 4', 4'... applied to coat the primer resin layer and having an adhesive force against the substrate smaller than an adhesive force of the primer resin layer against the substrate by an adhesion roll 5. In this manner, the circuit board 1 can be manufactured with a simple step by removing unnecessary portions of the conductive inks 4', 4'... to form the wiring layers 4, 4....
    • 要解决的问题:通过简单的步骤制造电路板来减少制造时间和制造成本。 解决方案:电路板包括:基板2,其形成为平板形状并具有布线形成表面; 形成在基板的布线形成表面上并且对基板具有预定粘合力的底漆树脂层3,3 ..., 以及形成在底漆树脂层上的布线层4,4 ...。 布线层通过去除与涂布底漆树脂层并且对基材的粘合力小于底漆粘合力的导电油墨4',4'之间的基板的布线形成表面接触而形成 树脂层通过粘合辊5抵靠基板。以这种方式,可以通过去除不需要的导电油墨4',4“...的部分的简单步骤来制造电路板1,以形成布线层4,4 (C)2012,JPO&INPIT
