PROBLEM TO BE SOLVED: To provide a highly reliable composite substrate capable of preventing peeling or deformation on an interface between different type ceramic materials or different type ceramic substrates, and to provide a manufacturing method thereof. SOLUTION: The composite substrate 1 is provided with an LTCC substrate 2, a high-permittivity ceramic substrate 3 having a permittivity higher than that of the LTCC substrate 2, and a resin layer 4 including a thermoplastic resin for bonding the ceramic substrate 2 and 3.
