ABSTRACT:
A surge absorber composed of a surge absorbing element comprising a silicon two-terminal thyristor element having a PNPNP or NPNPN junction structure and a bulk resistance element 12 comprising a material having a resistivity within a range of from 10.sup.-4 .OMEGA..multidot.cm to 10.sup.3 .OMEGA..multidot.cm and having a resistance value within a range of from 5.OMEGA. to 50.OMEGA., these elements being connected in series to form an integral body is disclosed. The inventive surge absorber requires reduced manhours for its production and is of a small size, but yet provides a large surge capacity.
