PROBLEM TO BE SOLVED: To provide a muscular electrical stimulation device capable of effectively stimulating abdominal muscles. A muscular electrical stimulation apparatus 1 is attached to a person's abdomen to apply electrical stimulation to the abdomen from an electrode section. The electrode portion is a first electrode extending from the main body portion 10 so as to be located in the person's right hand direction with respect to the center line 10a that is parallel to the height direction of the person and passes through the center of the main body portion 10 when attached to the center of the abdomen. And a second electrode group extending from the main body 10 so as to be located in the left-hand direction of the person with respect to the center line 10a. The first electrode group and the second electrode group are configured to be able to conduct electricity through a person, and each of the first electrode group and the second electrode group includes three or more electrodes. In the first electrode group and the second electrode group, the electrodes are arranged in a curved arc shape so as to be convex on the side opposite to the main body 10.
