Zusammenfassung:	The present invention provides a resin composition capable of obtaining a cured product having excellent impact resistance. A resin composition includes (A) an epoxy resin, (B) a thiol compound, and (C) magnetic powder, wherein the epoxy equivalent of component (A) is from 200 g/eq to 1000 g/eq, the (B) component is a thiol compound having two or more functional groups, and the ratio of the total number of thiol groups in (B) the thiol compound to the total number of epoxy groups in (A) the epoxy resin (thiol group/epoxy group) is from 0.3 to 1.0, and the cured product of the resin composition has an elastic modulus of 500 MPa or less at 25 DEG C and the elongation at the breaking point of the cured product of the resin composition at 25 DEG C is more than 30%.
