A grip-type electrocardiographic measuring device includes a main body portion that has a spheroid shape, a plate-shaped flange portion mounted on a side surface of the main body portion, a first electrocardiographic electrode disposed at a back surface side of the main body portion and making contact with one hand when the main body portion is gripped by the one hand, and a second electrocardiographic electrode disposed on a surface of the flange portion and making contact with a finger of the other hand when the flange portion is pinched by the other hand. The flange portion has flexibility and is bendable from a mounting portion on the main body portion.
