Process for production of long moldings and glass with molding

A process for producing elongated moldings having a variable cross-sectional area by injection molding, comprising the steps of:

• setting a metal molding on a first mold;
• laying a second mold on the first mold and forming a cavity by the first mold and the second mold in an area that includes the metal molding;
• narrowing one portion of the cavity formed between the second mold and the metal molding more than other portions of the cavity;
• and
• injecting molten resin into the cavity.

A glass with a molding, comprising:

• a glass base material;
• and
• a resin molding formed by injection molding on a peripheral edge of the glass base material,
• wherein the resin molding comprises an elongated molding having a variable cross-sectional area, the elongated molding has a portion of large cross-sectional area which has a concavely formed indented part, and a molding portion corresponding to the indented part is thinner than other molded portions.
