Seal member

A seal member formed in a strip shape having a long side extending in a length direction and a short side extending in a width direction in plan view, the seal member comprising:

• a substrate;
• a resin layer formed on one surface of the substrate;
• and
• a release sheet provided on the resin layer,
• wherein the resin layer includes a pressure-sensitive adhesive layer,
• the pressure-sensitive adhesive layer has a plurality of pressure-sensitive adhesive section rows, each pressure-sensitive adhesive section row of the plurality of pressure-sensitive adhesive section rows includes at least one pressure-sensitive adhesive section extending in the length direction of the substrate,
• the plurality of pressure-sensitive adhesive section rows are separated from each other in the width direction of the substrate such that a first end of each pressure-sensitive adhesive section row of the plurality of pressure-sensitive adhesive section rows in the length direction is separated from a first end of the substrate in the length direction,
• a distance between a first end of a first pressure-sensitive adhesive section row of an adjacent pair of pressure-sensitive adhesive section rows and the first end of the substrate in the length direction is (A), a distance between a first end of a second pressure-sensitive adhesive section row of the adjacent pair of pressure-sensitive adhesive section rows and the first end of the substrate in the length direction is (B), and (A) and (B) satisfy a relationship of (B)<(A),
• a ratio of a length of each pressure-sensitive adhesive section row of the plurality of pressure-sensitive adhesive section rows in the length direction to a width of each of the pressure sensitive adhesive section row of the plurality of pressure-sensitive adhesive section rows in the width direction is 1.3 or more, and
• a maximum peeling force to peel the release sheet from the resin layer by a tensile load perpendicular to an adhesive surface provided by the pressure-sensitive adhesive layer is 0.06 N/12.5 mm or more and 0.14 N/12.5 mm or less.
