发明名称 MULTILAYER CERAMIC SUBSTRATE AND METHOD FOR PRODUCING THE SAME
摘要 A multilayer ceramic substrate includes a ceramic laminated body including a plurality of ceramic layers stacked on each other, a resistor, and a resistor connecting conductor with a portion overlapping the resistor and an overcoat layer that covers the resistor located on a principal surface of the ceramic laminated body. An overcoat layer is made relatively thick during firing, thereby making cracks less likely to be caused, and after the firing step, the thickness of the overcoat layer is reduced by physically scraping down the surface of the overcoat layer, thereby reducing the trimming time. In the overcoat layer, a region that covers a portion in which a resistor overlaps a resistor connecting conductor is thicker than a region that covers the other portion.
