HOT MELT ADHESIVE AND FILTER ASSEMBLED USING SAME

The present invention provides an adhesive which is a hot melt adhesive that satisfies the following conditions (A), (B), and (C). (A) The melt viscosity at 190 DEG C, as measured using rotor No. SC4-27 in accordance with ASTM D3236-73, is from 1,000 mPa * s to 15,000 mPa * s (inclusive). (B) The softening point measured using a silicone oil as a heat medium in accordance with JIS K6863-1994 is from 130 DEG C to 170 DEG C (inclusive). (C) The temperature at which the displacement in the contraction direction reaches 0.05 mm due to the softening of a test piece is 90 DEG C or higher when a cylindrical test rod having a diameter of 3 mm is crimped onto the test piece cut at 5 mm square from a sample piece molded at a thickness of 2 mm in accordance with JIS K7196-1991, nitrogen gas flows through the test piece at a ratio of 100 ml/min, a load of 10 gf is applied, and the temperature is increased at a rate of 5 DEG C/min. 本发明提供一种粘接剂，其是满足下述的(A)、(B)及(C)的条件的热熔粘接剂。(A)依照ASTM D3236-73，使用转子No.SC4-27测定的190℃时的熔融粘度为1000mP
