Title: Imaging module, fabricating method therefor, and imaging device

Abstract: An imaging module includes an imaging chip including a micro-lens guiding incident light and an imaging element in a semiconductor substrate and converting the incident light into an electric signal, and a polarizing glass chip including a polarizing filter glass having a polarizer determining a polarization direction of the incident light arranged on a transparent substrate such that the polarizer faces the micro-lens and a spacer member connected to the polarizing filter glass to adjust a gap between the polarizer and the micro-lens of the imaging chip. In the imaging module, a melt-bonding surface of the spacer member is melt-bonded to the semiconductor substrate such that the polarizer of the polarizing glass chip and the micro-lens of the imaging chip are arranged close to each other via the gap, and the imaging element and the micro-lens of the imaging chip are sealed by the polarizing glass chip.
