PROBLEM TO BE SOLVED: To maintain a state that an antenna element part is adjusted in a required direction with higher stability by strengthening durability to rotation and tilting around an axis of the antenna element part.SOLUTION: A rod antenna 1 for a portable terminal has: a linear antenna element part 2; a holding part 3 which holds the antenna element part 2; and a contact conduction part 4 which pivotally supports the holding part 3 to be tiltable by a pivotally support part 5, and can fix the antenna element part 2 and the holding part 3 at a tilted state by energization of an elastic member 62 to the pivotally support part 5, in which a base part 41 of the contact conduction part 4 is inserted into a cylinder part 71 of a holder 7 whose contact part swelled inside is provided in a peripheral direction and formed to be slidable with the contact part, formed to be rotatable around the axis in the cylinder part 71, and formed like an approximate polygonal prism having a planar side faced 411 approximately planarly contactable with the contact part at a plurality of parts separated approximately at equal intervals in a circumferential direction. |
