The spacer of this embodiment is a spacer () formed of a resin molded body and inserted, in use, into a coolant water flow path () through an opening () of the coolant water flow path () that is formed around a plurality of cylinder bores () formed adjacent to each other in a cylinder block () of an internal combustion engine. The spacer () includes a spacer body () formed in a cylindrical shape to surround the cylinder bores (), and a protruding remaining portion () remaining after removal of a portion () necessary in molding and unnecessary after molding. The remaining portion () is formed at an end surface () positioned on a side close to the opening () of the spacer body ().
