PROBLEM TO BE SOLVED: To provide a polyolefin resin composition having heat generating characteristic by high frequency wave, giving moldings of excellent transparency, which becomes high frequency weldable by forming a layer on the surface of moldings, and to provide a molding using the resin composition. SOLUTION: This resin composition for high frequency welding comprises a polyolefin resin and a compound having a polar group (e.g. a polymer compound containing a quaternary ammonium salt in the molecule), has a value of the dielectric constant×dielectric dissipation factor (ε×tanη) being 0.01 or more in the measurement of dielectric properties at 23 deg.C and 40 MHz, and has a haze when molded to a film of 200μm thickness being 95% or more of that of the polyolefin resin alone molded at the same molding conditions. The molding is obtained by using the resin composition.
