Title: ELECTRONIC COMPONENT DEVICE
Abstract:
Provided is an electronic component device, which is not susceptible to the occurrence of wiring disconnection, and is capable of suppressing a resistance loss increase. An electronic component device 1 is provided with: an electronic component 3, which is embedded in a resin structure 2, and which has a portion exposed from a first main surface 2a of the resin structure 2; first wiring lines 4, 5, which are provided to reach the electronic component 3 from regions on the first main surface 2a of the resin structure 2, and which are electrically connected to the electronic component 3; second wiring lines 13, 14, 15, which are provided on the side of a second main surface 2b of the resin structure 2, and which are electrically connected to connection electrodes electrically connected to the first wiring lines; and low elastic modulus layers 8, 7, which are respectively provided at height positions between the first wiring lines 4, 5 and the exposed portion of the electronic component 3, said height positions being in regions where the first wiring lines 4, 5 are provided across the boundaries between the resin structure 2 and the electronic component 3, and which have an elastic modulus that is lower than that of the first wiring lines 4, 5, and are formed of a conductive material.
