PROBLEM TO BE SOLVED: To provide sealing material capable of reducing a portion to be discarded.SOLUTION: The sealing material 1, which is the sealing material for sealing an optical housing and a cover, includes sealing parts 2 to 5 capable of sealing the optical housing and the cover, and deformation parts 6a to 6c provided between the sealing parts 2 to 5. By bending and deforming the deformation parts 6a to 6c superficially, the sealing parts 2 to 5 can be changed from a folded state to an unfolded state. In the folded state, the sealing parts 2 to 5 are folded toward the inside of the sealing material 1. |
