[PROBLEMS] The present invention provides a polyester, film, and adhesive composition having excellent solvent solubility, heat resistance, adhesive strength, low dielectric constant and dielectric loss tangent, and excellent dielectric properties, and adhesive sheets, laminates, and printed wiring boards using the same. do. [Solution] The following monomers (A) and monomers (B) are contained as components, and when the total amount of all components is 100 mol%, the monomer (A) is 25 mol% or more and the monomer (B) is Polyester containing 10 mol% or more, and the total of monomer (A) and monomer (B) is 60 mol% or more. Monomer (A): polyhydric carboxylic acid component and/or polyhydric alcohol component having a polycyclic structure Monomer (B): polyhydric carboxylic acid component and/or polyhydric alcohol component having 10 or more consecutive carbon chains |
