1. A resin container, comprising:
a container body made of resin, configured to store liquid content, and including an outlet,
wherein the container body includes a body portion configured to store the liquid content,
the outlet of the container body has a smaller diameter than the body portion,
an inner wall surface of the container body that comes into contact with the liquid content includes a cyclic olefin copolymer and a linear low-density polyethylene resin,
at least a portion of a flow path of the liquid content upstream of the outlet has a diameter ranging from 0.5 mm to 8.0 mm,
a main monomer of the linear low-density polyethylene resin is an ethylene,
a comonomer of the linear low-density polyethylene resin introduces a short chain branch in the molecular structure, and
the short chain branch is introduced at a ratio of from 5 to 100 per 1000 units of structural units of the ethylene.
