PROBLEM TO BE SOLVED: To provide a screen panel that regulates force exerted on a straightening plate to be more uniform, and lowers a possibility of damage further.SOLUTION: A screen panel includes a plurality of ventilation paths formed between a plurality of straightening plates extending from a side in a depth direction to the other side. Each of the straightening plates includes a first straightening part extending from the side in the depth direction to the other side in the depth direction with a prescribed angle, a second straightening part extending from the other side in the depth direction to the side in the depth direction with a prescribed angle, a crown part where extended lines of the first straightening part and the second straightening part intersect, and a connecting part extending toward either or both of the side and the other side in the depth direction with regard to the crown part, for connecting ventilation paths formed between the plurality of straightening plates. The plurality of straightening plates are arranged in a direction along a surface orthogonal to the depth direction with a constant interval, and the crown part of each straightening plate is set on a virtual line connecting extended edges of the first straightening part and the second straightening part of the straightening plate on the crown part side, or on a side with the straightening plate located on the crown part side with respect to the virtual line.SELECTED DRAWING: Figure 1 |
