Abstract: A method of diagnosing a deterioration of a resin part includes: fabricating a deterioration detection part by adding a detection additional member to the resin part, in which the detection additional member is faster in progress of a deterioration than the resin part, and the adding the detection additional member includes bonding the detection additional member to a surface of the resin part or insert-molding the detection additional member to the resin part; incorporating the deterioration detection part into a portion, of a vehicle, where the resin part is to be incorporated; detecting, after an elapse of a predetermined period of time, a degree of the progress of the deterioration of the detection additional member; and estimating the degree of the progress of the deterioration of the resin part, based on data on a correlation between the deterioration of the detection additional member and the deterioration of the resin part.
