Abstract
Provided are an injection mold and an injection molding method by which a boundary line between a first material and a second material curved so as to be sharply bent like a round chamfered shape can be formed reliably in a desired position, and a molded article molded using the injection mold and the injection molding method. The sum of a length w of an inclined-part forming part 51a and a length y of a thinned-part forming part 51b in a width direction of a linear part or a width direction of a curved part is at least equal to a prescribed value, and the thinned-part forming part 51b forming the curved part has a second length y longer than a first length in the width direction of the curved part.
