Abstract
A method includes attaching an upper substrate to an upper surface of a sensor substrate, forming, on an upper surface of the upper substrate, a mask providing a first opening and a second opening communicating with the first opening, the second opening having a width that decreases with increase in a distance from the first opening, carrying out a sandblast process on the upper substrate exposed to an outside via the first opening and the second opening, allowing the sensor substrate to be exposed to the outside immediately below the first opening, and forming a slope on the upper substrate immediately below the second opening, and forming a first wiring member in contact with the exposed sensor substrate and a second wiring member being in contact with the slope and continuing to the first wiring member.
