Resin container and resin container connected body

A resin container, comprising:

• a container body including a storage portion configured to store liquid content and an outlet for the liquid content;
• and
• a lid configured to seal the container body by blocking the outlet,
• wherein the container body and the lid are made of a resin,
• the container body has a multilayer structure including a first layer being an innermost layer that comes into contact with the liquid content and a second layer that is in contact with the first layer from an outer side of the first layer,
• the first layer includes a cyclic olefin copolymer and a linear low-density polyethylene resin, with more of the cyclic olefin copolymer being included than the linear low-density polyethylene resin, and
• the second layer includes a low-density polyethylene resin,
• 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 ration of from 5 to 100 per 1000 units of structural units of the ethylene.
