Classification: CPC H | IPC H

Claim 10:
11. A multilayer substrate comprising:
semiconductor substrates each having a through hole of a plurality of through holes and a plated film on an inner surface thereof, the semiconductor substrates being laminated to each other, wherein:
a particle group formed from a plurality of adjacent conductive particles is present at least at a position where a first pair of the through holes face each other as viewed in a first direction corresponding to a plan view of the multilayer substrate, and
the multilayer substrate has a connection structure in which the first pair of the through holes are connected by the particle group, and the semiconductor substrates are bonded together by an insulating adhesive, wherein
the conductive particles in the particle group are disposed in a plane direction of the insulating adhesive,
a first conductive particle in the particle group includes a first surface directly contacting the insulating adhesive, the first surface protruding convexly towards the insulating adhesive as viewed in a second direction, and
the second direction is perpendicular to the first direction.
