Abstract:
A spacer (1) is provided with: projections (10) each having a frame-like part (S11), a plurality of columnar parts (S12) which have one ends contiguous to the frame-like part (S11) and which are formed so as to uprise from the frame-like part (S11), and an uprising end connection part (S13) which connects the other ends of the plurality of columnar parts (S12); and flexible connection parts (20) for connecting the frame-like parts (S11) of the respective projections (10) adjoining one another so that the plurality of projections (10) are linked to one another. The projections (10) which each have a three-dimensional shape and/or the flexible connection parts (20) which are elastically deformable are configured to have various shapes depending on the regions in the spacer (1). This configuration makes it possible to vary the thickness depending on the regions of the spacer (1) or to vary the flexibility depending on the regions of the spacer (1).
