PROBLEM TO BE SOLVED: To provide a small antenna capable of reducing mutual interference between a plurality of resonance sectors and obtaining high gain. SOLUTION: The antenna A1 comprises the resonance sectors E1 and E2, each having an inductance section 1 and a capacitance section 2 electrically connected in parallel, which are electrically connected in series. This antenna is constructed so that the section 1 and 1 have coil sections 1a and 1b, axes L1 and L2 of these sections 1a and 1b are aligned on a common straight line, and the part encircling the axes L1 and L2 are approximately included in a plane tilted to the axes L1 and L2.
