Abstract:
1. A 3D circuit module comprising: a support member having a frame in a periphery thereof and a recess; a coating layer for coating the frame and filling in the recess, the coating layer being made of resin material which is adhesive and has a softening temperature lower than a softening temperature of the support member; a wiring pattern formed on the coating layer and partly pressed thereinto, the wiring pattern having a first surface and a second surface opposite to the first surface, and including a first land over the frame, a second land within the recess, and a wiring part for connecting between the first land and the second land; and an electronic component having a first surface, a second surface opposite to the first surface, and side surfaces, accommodated in the recess and having a projecting electrode formed on the first surface of the electronic component, only the side surfaces and the first surface formed with the projecting electrode of the electronic component being bonded to the coating layer, wherein the projecting electrode is directly bonded to the first surface of the wiring pattern at the second land, the coating layer is disposed at least between the second surface of the wiring pattern and the support member, and the resin material encapsulates the electronic component and the wiring pattern and separates the second surface of the wiring pattern from surfaces of the recess.
