Epoxy resin composition, resin paste, film-type adhesive, printed wiring board, semiconductor chip package, and electronic device

An epoxy resin composition comprising

• component (A):
• an epoxy resin,
• component (B):
• at least one curing agent selected from the group consisting of a triazine skeleton-containing phenol-based curing agent, an active ester-based curing agent, and a cyanate ester-based curing agent, and
• component (C):
• a compound represented by the following formula (1) and/or a compound represented by the following formula (2):
• (In formulas (1), (2), R1 and R2 are each independently any one member selected from the group consisting of a hydrogen atom, a hydroxy group, a carboxy group, a cyano group, a nitro group, a halogen atom, an alkyl group having 1 to 20 carbon atoms and optionally having a substituent, and a cycloalkyl group having 6 to 20 carbon atoms and optionally having a substituent, R1 and R2 are the same as or different from each other, and R1 and R2 are optionally bonded to each other to form a condensed ring having no aromaticity;
• X is any one member selected from the group consisting of a hydrogen atom, an alkyl group having 1 to 20 carbon atoms and optionally having a substituent, an alkenyl group having 2 to 20 carbon atoms and optionally having a substituent, an aralkyl group having 7 to 20 carbon atoms and optionally having a substituent, and a heteroarylalkyl group having 4 to 20 carbon atoms and optionally having a substituent;
• each of Y and Z is any one member selected from the group consisting of a hydrogen atom, a halogen atom, a hydroxy group, a carboxy group, a cyano group, a nitro group, an alkyl group having 1 to 20 carbon atoms and optionally having a substituent, an alkoxy group having 1 to 20 carbon atoms and optionally having a substituent, an alkenyl group having 2 to 20 carbon atoms and optionally having a substituent, an aryl group having 6 to 20 carbon atoms and optionally having a substituent, an aryloxy group having 6 to 20 carbon atoms and optionally having a substituent, and an acyl group having 1 to 20 carbon atoms and optionally having a substituent, Y and Z are the same as or different from each other, and two or more Y moieties or two or more Z moieties are optionally bonded to each other to form a monocyclic ring or a condensed ring;
• and each of m and n is an integer of 1 to 4.)
