Abstract
Provided is an electrical wire-connecting structure, and a manufacturing method thereof, with which it is easy to ensure watertightness between a crimping terminal and an insulated electrical wire. A crimping terminal () having a tubular portion () is prepared in which a first cylindrical portion () into which a core wire portion () of an electrical wire () is inserted is formed with a smaller diameter than a second cylindrical portion () into which an insulation covering portion () of the electrical wire () is inserted, and an inner diameter of the second cylindrical portion () is in the range of 1.0 to 1.7 times an outer diameter of the insulation covering portion (). The electrical wire () is inserted into the tubular portion (), and the second cylindrical portion () and the insulation covering portion () are compressively crimped.
