Abstract

An objective is to provide an integrated optical module which can avoid positional change and separation of a PLC chip when humidity changes. Provided is an integrated optical module characterized in that the integrated optical module includes: a PLC chip; a seat bonded and fixed to part of a lower surface of the PLC chip with an adhesive which is applied to an adhesion surface of the seat; and a support portion supporting the seat, in which a water-repellent treatment portion is provided by masking an upper portion of the support portion with a water-repellent material. The water-repellent treatment portion is provided only around the seat for a predetermined width. The water-repellent treatment portion is provided around the seat for a width of 100 μm or more.
