Provided is an electronic device, and its manufacturing method, in which a cap body for sustaining vacuum is provided for each cell utilizing an existing fabrication process of electronic device. An Al film (151) is formed on a wafer (150) for cap and then patterned to form an annular film (144). A tubular part (142) surrounding a recess becoming a vacuum dome is formed by performing etching using the annular film (144) as a mask. Subsequently, a cut (152) is made in the substrate part (141) of the wafer (150) for cap and the wafer (150) for cap is mounted on a main wafer (100) on which an infrared area sensor is formed. Finally, the annular film (144) of the wafer (150) for cap is bonded to the annular film (118) of the main wafer (100) by compression thus forming an annular bonded part (15). |
