Hot-melt adhesive, reinforcing tape, and flexible flat cable having reinforced at conductor terminal with reinforcing tape

A hot-melt adhesive for reinforcing a conductor terminal of a flexible flat cable, comprising:

• 100 parts by mass of at least one member selected from the group consisting of
• (P1) a hydrogenated product of a block copolymer of an aromatic vinyl compound and a conjugated diene compound, wherein a content of a structural unit derived from the aromatic vinyl compound is not more than 65 mass % relative to a total of the content of the structural unit derived from the aromatic vinyl compound and a content of a structural unit derived from the conjugated diene compound,
• (P2) a hydrogenated product of a random copolymer of the aromatic vinyl compound and the conjugated diene compound,
• (P3) an acid-modified hydrogenated product of a copolymer of an aromatic vinyl compound and a conjugated diene compound, and
• (P4) an amine-modified hydrogenated product of a copolymer of an aromatic vinyl compound and a conjugated diene compound;
• and
• 1-100 parts by mass of (Q) a petroleum resin;
• and
• optionally 5-200 parts by mass of (R) an anti-blocking agent.

A reinforcing tape for reinforcing a conductor terminal of a flexible flat cable, comprising a hot-melt adhesive layer on one surface of an insulating film, wherein the hot-melt adhesive layer includes a hot-melt adhesive comprising at least one member selected from the group consisting of:

• (P1) a hydrogenated product of a block copolymer of an aromatic vinyl compound and a conjugated diene compound, wherein a content of a structural unit derived from the aromatic vinyl compound is not more than 65 mass % relative to a total of the content of the structural unit derived from the aromatic vinyl compound and a content of a structural unit derived from the conjugated diene compound,
• (P2) a hydrogenated product of a random copolymer of an aromatic vinyl compound and a conjugated diene compound,
• (P3) an acid-modified hydrogenated product of a copolymer of an aromatic vinyl compound and a conjugated diene compound, and
• (P4) an amine-modified hydrogenated product of a copolymer of an aromatic vinyl compound and a conjugated diene compound.
