Abstract
In a method for manufacturing a sensor apparatus having a sensor chip disposed in a recess of a case, after the sensor chip is disposed in the recess of the case, an opening portion of the recess is closed with a sheet member. The sheet member can prevent foreign matters from intruding an inside of the recess during manufacturing steps. After that, a through hole is formed in the sheet member. Accordingly, the inside and outside of the recess communicate with each other, and the sensor chip can detect an external environment of the recess such as atmospheric pressure.
