Abstract

Disclosed is a film-shaped adhesive. An embodiment of the film-shaped adhesive contains metal particles and has a shear viscosity at 110° C. of 30000 Pa·s or less. Another embodiment of the film-shaped adhesive contains metal particles and has a loss modulus at 110° C. of 200 kPa or less. Another embodiment of the film-shaped adhesive contains metal particles, a thermosetting resin, a curing agent, and an elastomer, in which a content of the metal particles based on the total amount of the metal particles, thermosetting resin, curing agent, and elastomer is 70.0% by mass or more, and a total content of the thermosetting resin and the curing agent is 13.0% by mass or more.

Claims (37)

1 . A film-shaped adhesive comprising metal particles,

wherein the film-shaped adhesive has a shear viscosity at 110° C. of 30000 Pa·s or less.

2 . The film-shaped adhesive according to claim 1 ,

wherein the film-shaped adhesive has a loss modulus at 110° C. of 200 kPa or less.

3 . A film-shaped adhesive comprising metal particles,

wherein the film-shaped adhesive has a loss modulus at 110° C. of 200 kPa or less.

4 . The film-shaped adhesive according to claim 1 ,

wherein the film-shaped adhesive further comprises a thermosetting resin, a curing agent, and an elastomer, and

a content of the metal particles is 70.0% by mass or more based on a total amount of the metal particles, the thermosetting resin, the curing agent, and the elastomer.

5 . The film-shaped adhesive according to claim 1 ,

wherein the film-shaped adhesive further comprises a thermosetting resin, a curing agent, and an elastomer, and

a content of the metal particles is 20.0% by volume or more based on a total amount of the metal particles, the thermosetting resin, the curing agent, and the elastomer.

6 . A film-shaped adhesive comprising:

metal particles;

a thermosetting resin;

a curing agent; and
