Original abstractThe present invention provides a handle for a container, a handle-equipped container, and a method for manufacturing same. It is accordingly possible to provide a container that has a cross-sectional shape that is substantially quadrangular and allows for exceptional storability, has favorable blow-molding properties, presents none of a variety of anomalies in the container and the handle, and has adequate strength to withstand drop impact. The present invention is characterized in comprising a polyester container, which has a finish part, a shoulder part, a body part, and a base part in the stated order from a top part; which has a concavity provided to a portion of the body part; and which has a handle-attaching convexity provided to the concavity; and a polyester handle attached to the handle-attaching convexity of the container. A space is provided between the handle and a wall surface that surrounds the handle-attaching convexity in the concavity. A transverse cross-sectional shape of the body part has a substantially quadrangular shape. The concavity is in a corner part of an upper half part of the body part, and the handle-attaching convexity is positioned in a concavity along a diagonal line L of the upper half part.
