ELECTRONIC-COMPONENT-EMBEDDED SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide: an electronic-component-embedded substrate in which vibration is reduced even if distortion occurs in an electronic component within an embedding layer by the application of a voltage, and in which the generation of audible sounds caused by vibration is prevented or reduced; and a method for producing the electronic-component-embedded substrate.SOLUTION: An electronic-component-embedded substrate 1 includes: a substrate B; a first electronic component 10 mounted on a main surface of the substrate B; and an embedding layer R which is provided on the main surface of the substrate B, and in which the first electronic component 10 is embedded. The first electronic component 10 is a laminated ceramic capacitor including a ceramic laminate having: a laminated section; a first side section and a second side section that sandwich the laminated section therebetween; two end surfaces that oppose one another; and a side surface that connects the two end surfaces. The first side section is located between the laminated section and the main surface of the substrate B in the thickness direction that is the direction orthogonal to the main surface of the substrate B. The elastic modulus of the embedding layer R is smaller than the elastic modulus of the substrate B.SELECTED DRAWING: Figure 2
