To provide a substrate holder capable of fully securing rigidity, even when a substrate is large-sized.

The substrate holder has a base which has flexibility and can be bent, a plurality of bars 3 which are arrayed on the base 11 that face a liquid crystal glass substrate 10, and adhesive layers 5, laminated and formed on opposite surfaces 4 of the respective bars 3 which face the liquid crystal glass substrate 10, and the adhesive layers 5 of the respective bars 3 are stuck detachably on the liquid crystal glass substrate 10. The plurality of bars 3 are united with the liquid crystal glass substrate 10, with the adhesive layers 5 interposed therebetween to constitute a structure; and since the respective bars 3 are extended in an X direction as plate bodies which are sectioned substantially in rectangular form to obtain sufficient rigidity, even when the liquid crystal glass substrate 10 is large-sized, there is no need for the base 11 itself to be enhanced in rigidity or made heavy.
