Screen coating jig and sealing structure of plate-shaped member

A screen coating jig for screen-coating a surface of a plate-shaped member having a protrusion to cross the protrusion with a sealing member, comprising:

• a jig body having higher rigidity than the sealing member to be placed on the surface of the plate-shaped member, wherein
• the jig body includes:
• a first surface facing the surface of the plate-shaped member;
• a second surface on an opposite side of the first surface;
• and
• a pair of dividing surfaces extending from the first surface to the second surface and dividing at least a part of the jig body into a first portion and a second portion, wherein
• the first surface includes a recess to be fitted to the protrusion of the plate-shaped member starting from intersection portions with the pair of dividing surfaces, wherein
• the pair of dividing surfaces has a uniform height from the first surface to the second surface, wherein
• a width between the pair of dividing surfaces is narrowed at a position corresponding to the recess.
