Container and method of manufacturing same

A method of manufacturing a container including a first member and a second member, and having a flow path for resin formed between the first member and the second member when the first member and the second member come into contact with each other, the method comprising the steps of:

• forming the flow path by causing the first member and the second member to come into contact with each other inside a mold;
• and
• bonding the first member and the second member to each other by causing the resin to flow in from an inflow opening to the flow path and to reach a filling target position, wherein
• an opening portion is formed in an exterior of the container,
• the opening portion is provided facing a position where the resin, which has flowed in from the inflow opening in the flow path, flows out beyond the filling target position, and
• a buffer portion which stores the resin having flowed out from the filling target position is provided in the flow path at a position facing the opening portion.

A flow path member, comprising:

• a first member,
• a second member;
• and
• resin filling a flow path that is formed between the first member and the second member when the first member and the second member come into contact with each other, wherein
• the resin bonds the first member and the second member to each other by reaching a filling target position after flowing from an inflow opening to the flow path,
• an opening portion is formed in an exterior of the container, the opening portion being provided facing a position where the resin, which has flowed in the flow path from the inflow opening, flows out beyond the filling target position, and,
• a buffer portion which stores the resin having flowed out from the filling target position is provided in the flow path at a position facing the opening portion.
