PROBLEM TO BE SOLVED: To provide a processing method in an air object using four sheets, where the sheets constituted of four sheets are sealed by thermal processing and an expansion state is kept longer than an air object composed of two sheets. SOLUTION: The sheets constituted of the four sheets includes a sheet (1), a sheet (2), a sheet (3), a sheet (4), a check valve (5), and an air layer (6). By the processing method in the air object using the four sheets, the sheets (1), (2), (3), (4) are thermally deposited, so as to be sealed. Then, the check valve (5) is attached to the sheets (2), (3) by thermal depositing. When a gaseous body is injected through the check valve (5), the air layer (6) is formed in the sheets (2), (3).
