We have investigated Josephson-quasiparticle (JQP) current in superconducting single-electron transistors in which charging energy {ital E}{sub {ital C}} was larger than superconducting gap energy {Delta} and junction resistances were much larger than {ital R}{sub {ital Q}}{equivalent_to}{ital h}/4{ital e}{sup 2}. We found that not only the shapes of the JQP peaks but also their absolute height were reproduced quantitatively with a theory by Averin and Aleshkin using a Josephson energy of Ambegaokar-Baratoff{close_quote}s value. {copyright} {ital 1996 The American Physical Society.}
