A multilayer ceramic substrate includes a base material layer including an aggregate of first particles containing a crystallized glass material and a first ceramic material, a constraining layer including an aggregate of second particles containing a second ceramic material that does not sinter at a temperature at which the crystallized glass material is melted, an intercalating layer including an aggregate of third particles containing a viscosity-decreasing substance that decreases the viscosity the melted crystallized glass material, and conductive films arranged along a main surface of at least one of the base material layer, the constraining layer, and the intercalated layer. The multilayer ceramic substrate also includes conductive films provided along a main surface of at least one of the base material layer, the constraining layer, and the intercalated layer.
