Abstract:
1. A method for producing a multilayer ceramic substrate, the method comprising the steps of: preparing an unfired multilayer ceramic substrate including a ceramic green laminated body including a plurality of ceramic green layers stacked on each other, the multilayer ceramic substrate also including a resistor, a resistor connecting conductor including a portion that overlaps the resistor, and an overcoat layer covering the resistor each located on at least one principal surface of the ceramic green laminated body; firing the unfired multilayer ceramic substrate; and reducing a thickness of the overcoat layer by physically scraping down a surface of the overcoat layer after the firing step; wherein in the step of reducing the thickness of the overcoat layer, a region of the overcoat layer that covers a portion in which the resistor overlaps the resistor connecting conductor is formed to be thicker than a region that covers other portions.
