ABSTRACT:
The manufacturing method for the air intake apparatus has a holding-portion forming step, a temporarily fixing step, and a joining step. In the holding-portion forming step, a holding portion is formed. In the temporarily fixing step, the porous member is held by the holding portion. In the joining step, the holding portion and the porous member are joined together. Thus, an air intake apparatus, in which the opening is reliably covered with the porous member, can be manufactured. In the air intake apparatus manufactured by this manufacturing method, a peripheral portion of the porous member is doubly sealed with the holding portion that is an outer edge part of the opening. Consequently, the opening is reliably covered with the porous member, so that intake noise is reliably reduced.
