PROBLEM TO BE SOLVED: To prevent degradation of discharge characteristics, by suppressing contamination due to scattering matter in a surge absorber. SOLUTION: The surge absorber includes: a glass tube 2; a pair of sealing electrodes 3 which close both end openings of the glass tube 2 and seal discharge gas inside; a planar insulator 4 with the pair of sealing electrodes 3 in a contact state arranged on both ends and housed in the glass tube 2. The insulator 4 is obliquely housed with respect to an axial line of the glass tube 2, and includes a deformation part 4a for forming a space, in which a virtual line parallel to the axial line can pass through without being interrupted, in an intermediate part.
