To provide a pneumatic shaped body with a short manufacturing period and a low manufacturing cost, excellent in perceptivity and expression, capable of accurately reproducing a plane image.

A film structure is formed in a bag state by preparing a front sheet 9 on which an image is printed on its surface and a rear sheet 10 on which a reverse image is printed, so that both back surfaces may face each other, and so that a peripheral section 13 of the front sheet and a peripheral section 14 of a rear sheet may be connected via a side sheet 11. Moreover, bridges 12 are provided between the front sheet 9 and the rear sheet 10, and expansion is restrained and irregularity arises on surfaces of the front sheet 9 and the rear sheet 10. Thereby, as the film structure becomes 3-dimensional like a relief when expanded, impression of the printed image is not spoiled.
