Abstract
A substrate laminated body is formed by joining a first substrate for forming a part of a device and a second substrate for forming another part of the device. The first and second substrates are joined by a method comprising: a temporarily joining step of arranging an adhesive agent outside a device forming region and temporarily joining the device forming regions of the first substrate and the second substrate to be held in a non-contact state, and a finally joining step of forming a film so as to fill a gap between the device forming regions in the non-contact state and finally joining the first substrate and the second substrate by way of the film.
