Title:
OPTICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/008255
Kind Code:
A1
Abstract:
In order to realize an optical device that directly joins an optical member and a sensor while suppressing leakage of an adhesive agent to a light-receiving element, provided is an optical device (10) which includes: a substrate (11); a sensor (12) that is mounted to the substrate (11) and that has an upper surface on which an element forming part (16) having a light-receiving element for detecting light disposed thereon is formed; an optical member (13) that opposes the upper surface of the sensor (12) and that guides light to the element forming part (16); a first joining member (14) that joins, on the upper surface of the sensor (12), a portion other than the light-receiving element that is effective in the element forming part (16) and the surface on the sensor (12) side of the optical member (13); and a leakage prevention mechanism (15) that prevents the first joining member (14) from leaking, on the upper surface of the sensor (12), onto the light-receiving element that is effective in the element forming part (16).
