A resin composition that can be used for an optical waveguide cladding, in which a flow ratio of a resin layer formed from the resin composition as calculated by the following Method 1 is equal to or more than 6% and equal to or less than 200%. [Method 1] A sample is formed such that a thickness of the resin layer formed from the resin composition is 100 μm, the sample is cut into a circle having a diameter of 1 cm to obtain a sample for measuring a flow ratio. The sample for measuring a flow ratio is sandwiched between slide glasses and laminated using a laminating machine under conditions of a temperature of 100° C., a pressure of 5.0 MPa, and a time of 180 seconds, areas of the resin layer before and after lamination are measured, and the flow ratio [%] is calculated from the following Expression (I): Flow ratio [ % ] = [ ( Area of resin layer after lamination - Area of resin layer before lamination ) / Area of resin layer before lamination ] × 100.
