A electromagnetic shielding member whose tubular shape is maintained with a simpler structure. The electromagnetic shielding member includes a pluralities of first and second protrusions that are respectively formed at first and second edges in a circumferential direction of a metal plate member that has been bent into a tubular shape. The plurality of first protrusions are formed, spaced apart in a longitudinal direction, each of the first protrusions having a first wider portion closer to its tip than the first narrower portion. The plurality of second protrusions are formed, spaced apart in the longitudinal direction, each of the second protrusions having a second wider portion closer to its tip than the second narrower portion. The metal plate member is formed into the tubular shape so that the first protrusions and the second protrusions are engaged with each other and are interposed with each other.
