Pressure sensor, microphone, ultrasonic sensor, blood pressure sensor, and touch panel

A pressure sensor comprising:

• a support portion;
• a membrane part which has flexibility and includes a first end portion supported by the support portion, a first area positioned between a center of the membrane part and the first end portion, and a second area positioned between the first area and the first end portion where a sensor portion is not provided;
• and
• a first sensor portion which is provided at the first area and includes a first magnetic layer, a second magnetic layer and a first intermediate layer provided between the first magnetic layer and the second magnetic layer,
• wherein the second area includes a first portion which extends in a first direction from the center toward the first end portion and a second portion which is connected to the first portion and extends in a second direction from the first area toward the first sensor portion, and
• a first end-side distance between the first area and the first end portion is shorter than a first center-side distance between the second area and the center of the membrane part.
