Abstract: An antenna comprises the followings: a base substance provide on a substrate 8; a conductive film made on the base substance; and a gap 5 that electrically divides the conductive film into a first conductive film 6 and a second conductive film 7. The first conductive film 6 is connected to a power supply section provided on the substrate 8, and the second conductive film 7 is connected to a ground section 9 by way of a conductor. The power supply section, the first conductive film 6, the gap 5, the second conductive film 7, a conductor 11, and the ground section 9 are serially connected in this sequence.

Abstract: An electronic component is provided in which: impact-absorbing layers are provided so as to cover at least the corner portions of both end portions of a base which is made of an insulating mixture of ceramic and glass; a conductive film is formed so as to cover the surface of these impact-absorbing layers and the surface of the base; the portions of this conductive film which cover the surfaces of the impact-absorbing layers are formed into electrodes; and a resistance-adjusting groove is provided in an other portion of the conductive film than the portions serving as the electrodes.

Abstract: A circuit protector comprising a substrate, a conductive layer formed around the substrate, a narrowed portion formed on the conductive layer at a certain part, terminals formed at both ends of the substrate. The substrate has 1-30% pores in a unit surface area in a vicinity of its surface. The present invention also relates to a mounting structure of the circuit protector onto a circuit board.
