- the height position of 30b is different from the height position of a pair of main surfaces of the adjacent first conductor layers 13. More specifically, the first main surface 30a of the electronic component 30 is higher than the main surface above the first conductor layer 13 (on the third conductor layer 15 side), and the second main surface 30b of the electronic component 30 is It is higher than the main surface below the first conductor layer 13 (on the second conductor layer 14 side) (that is, corresponding to the first main surface 11a of the first insulating layer 11). As a result, even when the electronic component built-in substrate 1 receives an external force, the electronic component 30 can be prevented from being damaged due to the external force.
- the electronic component built-in substrate 1 according to the present embodiment has been reduced in height in response to the recent demand for lowering the height of electronic devices. That is, the thickness of the electronic component built-in substrate 1 is very small as compared with the conventional electronic component built-in substrate. Therefore, the electronic component built-in substrate 1 is easily affected by external force.
- the influence which the electronic component built-in substrate 1 receives changes with the position where the electronic component built-in substrate 1 receives external force, the direction of the external force, and the magnitude thereof. However, the region in which the electronic component 30 is built and its periphery are places where the influence of external force tends to concentrate.
- the first insulating layer 11 and the second insulating layer 12 are laminated and the first conductor layer 13 is formed in the vicinity of the interface as in the electronic component built-in substrate 1, the first insulating layer 11
- the electronic component 30 disposed at the interface between the first insulating layer 11 and the second insulating layer 12 is easily affected. More specifically, when an external force that causes a positional shift between the main surface on one side and the main surface on the other side along the main surface direction of the electronic component built-in substrate 1 is received, the electronic component built-in substrate 1.
- the first main surface 11a of the first insulating layer 11 and the main surface of the second insulating layer 12 facing the first main surface 11a are most easily affected, and their relative positions change. Receive external force.
- the first conductor layer 13 provided on the first main surface 11a of the first insulating layer 11 receives an external force. And it is thought that an external force is propagated along the 1st main surface 11a via the 1st conductor layer 13, and the electronic component 30 is also influenced by it.
- the first conductor layer 13 often has higher rigidity than the surrounding first insulating layer 11 and second insulating layer 12, and in this case, it is considered that the ability to propagate external force is particularly high.
- the electronic component 30 and the adjacent first conductor layer 13 are at the same height when viewed in the stacking direction, the external force propagated by the first conductor layer 13 is also propagated to the electronic component 30.

- the stacking direction of the first electrode layer 31A and the second electrode layer 31B and the dielectric layer 32 is such that the first insulating layer 11 and the second insulating layer 12 If the stacking directions are the same, there is a possibility that the electronic component 30 is greatly affected by the external force.
- both the height positions of the first main surface 30a and the second main surface 30b of the electronic component 30 are a pair of adjacent first conductor layers 13. It is different from the height position of the main surface.
- the height position of a pair of main surface (the 1st main surface 11a and the 2nd main surface 11b) of the electronic component 30 and a pair of main surface of the adjacent 1st conductor layer 13 are the same.
- the propagation direction of the external force by the first conductor layer 13 and the extending direction of the pair of main surfaces of the electronic component 30 can be made different. Therefore, the influence of the external force propagated by the first conductor layer 13 received by the electronic component 30 can be reduced. Therefore, it is possible to suppress the electronic component from being affected by an external force.
- the electronic component 30 is laminated on the first main surface 11 a of the first insulating layer 11 via the adhesive layer 40. And by having such a structure, the height position of the lower surface of the 1st conductor layer 13 and the height position of the 2nd main surface 30b of the electronic component 30 mutually differ. As described above, the electronic component 30 is provided on the adhesive layer 40 on the first main surface 11a of the first insulating layer 11, so that the first main surface 11a of the first insulating layer 11 and the first The adhesive layer 40 can relieve a force that causes a positional deviation between the main surface of the second insulating layer 12 facing the main surface 11a.
- the adhesive layer 40 can alleviate this. Therefore, it is possible to further suppress the electronic component 30 from being affected by an external force.
- the effect of being able to suppress the influence of external force in the electronic component 30 is significant when the thickness of the first conductor layer 13 is substantially uniform as in the electronic component built-in substrate 1.
- distribution to the other direction of the external force which propagates along the extension direction of the 1st conductor layer 13 is suppressed. Therefore, the first conductor layer 13 may be propagated to the electronic component 30 in a state where the magnitude of the external force is maintained. Therefore, when the thickness of the first conductor layer 13 is substantially uniform, the height position of the main surface of the electronic component 30 is different from the height position of the pair of main surfaces of the adjacent first conductor layer 13. Thus, the effect of reducing the influence of the external force propagated by the first conductor layer 13 received by the electronic component 30 becomes significant.
- the first main surface 11a of the electronic component 30 is higher (on the third conductor layer 15 side) than the upper surface of the first conductor layer 13, and the first conductor layer 13
- the example in which the 2nd main surface 11b of the electronic component 30 is higher than the lower surface (1st main surface 11a of a 1st insulating layer) is shown.
- the height position of the main surface of the electronic component 30 and the height position of the pair of main surfaces of the adjacent first conductor layer 13 are different from each other, the effect of suppressing the influence of the external force applied to the electronic component 30 is reduced. can get.
- the effect of suppressing the influence of the external force applied to the electronic component 30 Is obtained. That is, even if the height position of the second main surface 11b of the electronic component 30 is the same as the height position of the lower surface of the adjacent first conductor layer 13, the height of the first main surface 11a of the electronic component 30 is the same. Since the position and the height position of the upper surface of the adjacent first conductor layer 13 are different, the influence of the external force applied to the electronic component 30 can be suppressed.
- the difference between the height position of the first main surface 30a of the electronic component 30 and the height position of the main surface (upper surface) of the first conductor layer is preferably 10 ⁇ m or less.
- the height position of the first main surface 11a of the electronic component 30 and the main surface (upper surface) of the first conductor layer is very thin.
- the stress derived from the external force may concentrate on the electronic component 30.
- the thickness of the second insulating layer 12 is greatly different between the upper portion of the electronic component 30 and the periphery thereof, and stress may be concentrated on the electronic component 30.
- the stress concentration on the electronic component 30 can be reduced by setting the difference between the height position of the first main surface 11a of the electronic component 30 and the height position of the main surface (upper surface) of the first conductor layer to 10 ⁇ m or less. Can be suppressed.
- the difference is preferably 10 ⁇ m or less. Even when the height position of the second main surface 30b of the electronic component 30 and the height position of the main surface (lower surface) of the first conductor layer are greatly different, the electronic component 30 is derived from an external force. Stress can be concentrated. Therefore, concentration of stress on the electronic component 30 can be suppressed by setting the difference in height position to 10 ⁇ m or less.
