  • Patent number: 10356908
    Abstract: An electronic component containing substrate includes a substrate, a first electronic component mounted on a main surface of the substrate, and an embedment layer provided on the main surface of the substrate and embedding the first electronic component. The first electronic component is a multilayer ceramic capacitor including a ceramic multilayer body including a layered portion and a first side portion and a second side portion between which the layered portion lies and having two end surfaces opposed to each other and side surfaces connecting the two end surfaces to each other. The first side portion is located between the layered portion and the main surface of the substrate in a direction of thickness which is a direction perpendicular to the main surface of the substrate. The embedment layer is smaller in elastic modulus than the substrate.
