Affixed to a projection (111) of a glass substrate (110) included in a liquid crystal module (100) are a first ACF (150a), which has low surface tack strength but high connection reliability, and a second ACF (150b), which has high component attaching capability attributed to high surface tack strength. With these, an LSI chip (130), electronic components (150), etc., are mounted on the glass substrate (110), so that high-speed electronic component mounting can be achieved while ensuring connection reliability.
