In order to provide a magnetic field measuring apparatus facilitating the pressure control in a gas cell, or capable of inspecting the internal pressure of the gas cell without using any special process, the magnetic field measuring apparatus is configured such that a process layer of the magnetic field measuring apparatus has such a structure that includes a first hollow portion and a second hollow portion provided opposed to first hollow portion with a first isolation wall interposed therebetween. Alternatively, a method for manufacturing the magnetic field measuring apparatus includes breaking the first isolation wall after generating alkali metal (FIG. 17 and FIG. 20).
A magnetic field measuring apparatus comprising:
A method for manufacturing a magnetic field measuring apparatus including a first sealing member, a second sealing member, and a process layer sealed by the first sealing member and the second sealing member, wherein the process layer includes a first hollow portion and a second hollow portion provided with a first isolation wall interposed therebetween, the method comprising:
A method for manufacturing a magnetic field measuring apparatus including a first sealing member, a second sealing member, and a process layer sealed by the first sealing member and the second sealing member, wherein the process layer has a structure in which the first process member and the second process member are stacked, and a first hollow portion is provided inside of the first process member and inside of the second process member, and a second hollow portion is provided inside of the first process member with a first isolation wall interposed therebetween, the method comprising:
