A multilayer coil component includes a component element assembly in which an inner conductor is disposed and an outer electrode disposed on the surface of the component element assembly. The component element assembly includes a first dielectric glass layer in which the inner conductor is embedded and second dielectric glass layers that are thin layers disposed on respective principal surfaces of the first dielectric glass layer. The primary component of each of the first dielectric glass layer and the second dielectric glass layers is formed of a glass material and has a filler component containing at least quartz, and the second dielectric glass layers have a lower quartz content than the first dielectric glass layer.
