A capacity detection type sensor element (10) includes a rectangular diaphragm (11) and a flat rear electrode (12) which are arranged to oppose each other. The capacity detection type sensor element (10) further includes fixed portions (14) each arranged to be adjacent to a side of the diaphragm (11) and having a side of a predetermined length at the side adjacent to the diaphragm (11). The rear electrode (12) is supported by the fixed portions (14) so as to form a space (13) between the rear electrode (12) and the diaphragm (11). The rear electrode (12) is an octagon as a whole having straight lines between adjacent fixed portions not supported by the fixed portions (14).
