Abstract (in Japanese) (See Japanese page) 
(in English) This paper focuses on the relationship between the number of developers involved in a source file and its code quality, and examines the differences of single-authored files from multi-authored files in terms of their metrics---size and coupling. The empirical study collects source files from Java open source software products, and compares the size metric values and coupling metric values between two sets: single-authored files vs. multi-authored files. As a result, the following two finding are presented: (1) single-authored files slightly tend to be smaller-sized than multi-authored ones;
(2) single-authored files are likely to be more independent than multi-authored ones. These findings would be useful basis to appropriately explain the
previous work's result that single-authored files are not likely
to be fault-prone than multi-authored ones.
