Abstract
A filter is compressed between facing surfaces of a first configuration component and a second configuration component, and a molten resin is poured in such a compressed state. Injection molding of the first configuration component and the second configuration component, joining of the configuration components, and sealing of the circumference of the filter are performed by a pair of metal molds.

A manufacturing method of a liquid supply component in which a first configuration component and a second configuration component are joined together such that a first opening portion of the first configuration component and a second opening portion of the second configuration component face each other, and thus, a liquid supply path communicating through the first opening portion and the second opening portion is formed, the method comprising:
- a first step of performing injection molding with respect to the first configuration component in a first position between a pair of metal molds, and of performing injection molding with respect to the second configuration component in a second position between the pair of metal molds;
- a second step of opening the pair of metal molds such that the first configuration component remains in one metal mold of the pair of metal molds, and the second configuration component remains in another metal mold of the pair of metal molds, and of relatively moving the pair of metal molds such that the first configuration component and the second configuration component face each other;
- a third step of interposing a sintered nonwoven fabric filter between the first opening portion and the second opening portion, the sintered nonwoven fabric filter having voids formed by fibers;
- a fourth step of closing the pair of metal molds such that a circumferential portion of the sintered nonwoven fabric filter is compressed between facing surfaces of the first configuration component and the second configuration component;
- and
- a fifth step of pouring a molten resin between the facing surfaces so at to contact the circumferential portion of the sintered nonwoven fabric filter,
- wherein the molten resin is a resin capable of entering the voids of the sintered nonwoven fabric filter, and
- wherein in the fourth step, a size of the voids of the circumferential portion is reduced by compression of the sintered nonwoven fabric filter so that the molten resin is suppressed from entering the voids from a surface of the circumferential portion.
