    Do you mean the mid-surface of the entire part (for simulation)? Or the mid-plane (use midplane option in Plane feature)?

    Midplane option of the plane feature will work fine if you just want to get a plane in between two planar surfaces. If you want a middle surface for the entire part you'll need to use Offset with a value equal to half the thickness.

    Yes i mean mid-surface of the entire part for shell meshing, i tried Offset all part but left and right ears of part was drawn on different planes. So i could not.

    If it’s all one part you should be able to use offset surface. Can you share the URL?

    This part looks like it's sheet metal, but it's not really modeled like sheet metal, which makes shell meshing a bit sketchy. The material thickness varies anywhere from .77mm to 4.2mm. So if you wanted a true midsurface, you'd have to stitch together multiple Offset surfaces.
