The adhesive sheet of this invention is a (A) high molecular weight component, (B1) thermosetting component whose softening point is less than 50 degreeC, (B2) thermosetting component whose softening point is 50 degreeC or more and 100 degrees C or less, and (C) softening point which is 100 degrees C or less. It consists of a resin composition containing a phenol resin, and based on 100 mass% of this resin composition, 11-22 mass% of said (A) high molecular weight components, and the said (B1) softening point 10-10-thermosetting components of less than 50 degreeC. 20 mass%, the said (B2) softening point contains 10-20 mass% of thermosetting components which are 50 degreeC or more and 100 degrees C or less, and 15-30 mass% of phenol resins whose said (C) softening point are 100 degrees C or less. |
