PROBLEM TO BE SOLVED: To provide a door hinge allowing a large effective size of a door opening part. SOLUTION: A center distance between a door 40 and a pivot 16 is reduced as much as possible when the door 40 is opened by 90 degree without disturbed by the shaft 16, by extending a first hinge piece fixed to one side edge surface of the door 40 in parallel with the tangential direction of the shaft 16. The effective size L of a door opening part 50 is enlarged by providing the door opening part 50 with a mortise part 51 for storing the door 40 opened by 90 degree, and a recessed part for storing a hinge 10.
