PURPOSE:To provide a medical component excellent in the qualities of anti- radioactive rays, transparency and heat resistance by forming it out of resin whose constituent element I is a predetermined mol.% of the whole of a polymer and whose constituent element II is a predetermined mol.% of the whole of the polymer and whose weight-average molecular weight in polystyrene is within a predetermined range. CONSTITUTION:A medical component is formed out of resin whose constituent element I shown by a chemical formula I is 30-98mol.% of the whole of a polymer and whose constituent element II shown by a chemical formula II is 70-2mol.% of the whole of the polymer and whose weight-average molecular weight in polystyrene is more than 1X10<3> and less than 5X10<6>. However, R1 in the formula is an alkyl group with 1-8 carbon atoms, or a cycloalkyl group with 3-12 carbon atoms, and R2, R3, R4 are each an hydrogen atom or an alkyl group with 1-8 carbon atoms. |
