A manufacturing method for a camera module including a multilayer body in which an image sensor IC and a lens are arranged with an optical path provided in the multilayer body being disposed therebetween includes a first step and a second step. In the first step, the multilayer body is formed by stacking and combining flexible sheets. In the second step, a through hole is formed in flexible base material layers that constitute a portion of the multilayer body to form the optical path defined by the through hole.

Manufacturing method for camera module

A camera module includes an image sensor IC, a resin multilayer board including thermoplastic resin layers stacked in a direction perpendicular or substantially perpendicular to a light receiving surface of the image sensor IC, a mounting electrode which is stacked on the thermoplastic resin layer and on which the image sensor IC is mounted, and a via-hole conductor electrically connected to the mounting electrode. The resin multilayer board includes a flat plate portion including a surface on which the mounting electrode is mounted, and a rigid portion including a greater number of thermoplastic resin layers than that of the flat plate portion, and the via-hole conductor is arranged in the flat plate portion so as to avoid the thermoplastic resin layer on which the mounting electrode is stacked.

Camera module

There is disclosed a method of producing a ceramic multilayer substrate by laminating a plurality of glass-ceramic green sheets made of a glass-ceramic containing an organic binder and a plasticizer to form a laminate; and firing the laminate; further comprising: applying to or overlaying on the surfaces of the glass-ceramic green sheets inorganic compositions, the sintering temperature of the inorganic compositions being higher than that of the glass-ceramic green sheets; laminating a plurality of the glass-ceramic green sheets having the inorganic compositions applied to or overlaid on the surfaces of the glass-ceramic green sheets respectively, to form a part of the laminate; and laminating a plurality of the glass-ceramic green sheets to form the other part of the laminate.
