A functional element-mounted module can be decreased in size and requires no costly and special members for a light transition member. A substrate is used, on which an optical functional element having an optical function part and bonding pads therearound is mounted by wire bonding, with an upper face of the element upward. A bank to dam a liquid sealing resin is provided around the optical functional element on the substrate, and the liquid sealing resin is dropped and filled between the optical functional element and the bank such that the bonding pads and partial gold wires for the wire bonding are exposed. A package-component member having a hole corresponding to the optical functional element is abutted to the bank such that the hole is opposed to the function part of the functional element. Thereby, the package-component member is contacted to the liquid sealing resin. The package-component member is fixed to the substrate by curing the liquid sealing resin, and the bank is cut away.

1. A method for producing a functional element-mounted module, said method comprising: providing a substrate on which a functional element having a given function part and bonding pads therearound on a function part-side face of the element body is mounted by wire bonding, with the function part-side face upward;providing a bank to dam a liquid sealing resin near the functional element on the substrate, dropping the liquid sealing resin between the functional element and the bank, filling the liquid sealing resin between the functional element and the bank such that the bonding pads and partial wires for the wire bonding are exposed;abutting a package-component member having a hole formed through the package-component member and placed directly above the functional element to the bank such that the hole is opposed to the function part of the functional element, thereby bringing a lower face of the package-component member that is opposed to a top surface of the substrate into contact with the liquid sealing resin such that the bonding pads and the partial wires for the wire bonding remain exposed;providing a protective cover film peelable from the package-component member on the package-component member to cover the hole;fixing the package-component member onto the substrate by curing the liquid sealing resin that is in contact directly with both of the substrate and the package-component member; andcutting away the bank. 2. The method for producing the functional element-mounted module according to claim 1, wherein the hole of the package-component member is formed of almost the same size as the functional element. 3. The method for producing the functional element-mounted module according to claim 1, wherein a metallic film which enables wire bonding with gold and protects an Al-based electrode is provided on a bonding pad of the functional element.
