Claim 0:
1. An adhesive resin composition consisting of:
more than 50 parts by mass and 99.5 parts by mass or less in a solid content of an acid-modified polyolefin resin (A) having a melting point of 50 to 100° C.;
0.5 parts by mass or more and less than 50 parts by mass in a solid content of an epoxy resin (B) having a novolac structure; and
an organic solvent (C),
wherein said acid-modified polyolefin resin (A) has a methyl group and an ethyl group on a side chain,
said organic solvent (C) includes toluene and methyl ethyl ketone, and
said epoxy resin (B) having the novolac structure is a bisphenol A novolac epoxy resin represented by formula (1):, wherein, R1 to R6 each are independently a hydrogen atom or a methyl group, n is an integer of 0 to 10, and RX is a group having an epoxy group, and
R1 to R6 satisfy at least any one of (i) to (iii):
(i) both of R1 and R2 are a methyl group;
(ii) both of R3 and R4 are a methyl group; and
(iii) both of R5 and R6 are a methyl group, and

wherein in dynamic viscoelasticity measurement, an adhesive resin film formed including said adhesive resin composition has a storage modulus value at 60° C. of 1.0×106 to 1.0×108 Pa and a storage modulus value at 150° C. of 1.0×104 to 1.0×108 Pa.
